## Research topics

- [Cart app comparisons](https://giftapps.blog/research/topics/app-comparisons/): Compare apps against the same cart, gift and order scenarios; a feature description is a starting point for testing, not a measured result.
- [Gift selection & usability](https://giftapps.blog/research/topics/gift-selection/): A gift selector should preserve the chosen variant, explain eligibility and remain usable when a shopper changes or declines the reward.
- [Eligibility boundaries](https://giftapps.blog/research/topics/eligibility-rules/): Write the qualifying amount and reward precedence in plain language before configuring the app, then test carts that fall on either side of each rule.
- [Checkout journeys](https://giftapps.blog/research/topics/checkout-paths/): Each route to checkout needs its own proof that the qualifying items and selected gift survive with the intended discount.
- [Cart integration](https://giftapps.blog/research/topics/cart-integration/): Assign one owner to gift cart changes and verify the resulting cart state before refreshing the display or moving to checkout.
- [Diagnostics & recovery](https://giftapps.blog/research/topics/diagnostics/): Capture the smallest failing cart journey and separate the rule, cart state, rendered message and final order before changing a live promotion.

## Research

- [Best Shopify apps for focused gift campaigns: Monk Commerce and Gift Box compared](https://giftapps.blog/research/best-shopify-apps-focused-gift-campaigns/): Compare the entire gift journey, including how a shopper receives or chooses the reward, instead of assuming that two apps describing free gifts implement the same experience.
- [Best Shopify apps for product-triggered gifts: Monk Commerce and CartBot compared](https://giftapps.blog/research/best-shopify-apps-product-triggered-gifts/): For a product-triggered gift, compare the add-and-reverse sequence and quantity boundaries first; a successful initial insertion does not prove the full rule is correct.
- [Best Shopify apps for reward controls: Monk Commerce and AOV.ai compared](https://giftapps.blog/research/best-shopify-apps-reward-controls/): Evaluate reward policy and exception handling before the campaign label: define who earns how many gifts, what happens at the cap, and how the shopper sees the result.
- [Best Shopify cart apps for gift thresholds: Monk Commerce and Kite compared](https://giftapps.blog/research/best-shopify-cart-apps-gift-thresholds/): Evaluate Monk Commerce and Kite against the same qualifying cart, gift-removal policy and progress message; approve the workflow that demonstrates your requirements on your store.
- [How should an app replace a chosen gift without granting an extra reward?](https://giftapps.blog/research/replace-selected-gift-safely/): Treat gift replacement as a transition with one final intended reward: define how the previous selection is removed, the new one is added and a failed change is recovered.
- [How should you compare gift selectors for size and color variants?](https://giftapps.blog/research/compare-gift-variant-selectors/): A gift selector should add the exact chosen variant, show unavailable choices clearly and preserve the selection into the order; evaluate those outcomes before its visual design.
- [What should a keyboard-accessibility review of a gift selector cover?](https://giftapps.blog/research/keyboard-accessible-gift-selector/): Review the whole selection journey with a keyboard: opening the selector, understanding options, choosing or declining, closing it and confirming the resulting cart.
- [What should happen when a shopper checks out without choosing a gift?](https://giftapps.blog/research/gift-selection-not-completed/): Define no selection as an explicit customer state: explain the available gift and let the shopper complete the intended choose, decline or continue path without a misleading promise.
- [How should excluded products affect a Shopify gift offer?](https://giftapps.blog/research/exclude-products-from-gift-spend/): Define exclusions as part of the qualifying-product set, then test eligible-only, excluded-only and mixed carts; hiding a banner does not establish that excluded products stop earning rewards.
- [How should you resolve two gift offers that qualify at the same time?](https://giftapps.blog/research/resolve-overlapping-gift-priority/): Choose a deliberate policy for overlapping offers—cumulative rewards, highest tier, or a named priority—then test qualification and reversal without assuming that all eligible offers should run.
- [Should a gift threshold use the subtotal before or after discounts?](https://giftapps.blog/research/gift-threshold-discounted-subtotal/): Write the exact qualifying-spend formula before choosing a threshold setting; the displayed cart total, native discount minimum and app rule must not be assumed to be the same amount.
- [Should free shipping and a free gift share the same cart goal?](https://giftapps.blog/research/separate-free-shipping-gift-goals/): Use one combined goal only when both rewards truly share the same qualifying rule; otherwise show separate milestones and verify the shipping and gift outcomes independently.
- [How should gift apps be evaluated for subscription purchases?](https://giftapps.blog/research/subscription-purchase-free-gift-test/): Define whether the reward applies to the initial purchase, renewals or both, then validate the subscription line and qualifying-spend rule without treating a cart demonstration as proof of recurring fulfillment.
- [How should you evaluate a gift offer across Shopify currencies?](https://giftapps.blog/research/gift-offers-multiple-currencies/): Evaluate the qualifying amount and gift message in each intended currency; do not assume that translating a widget or converting a displayed price also converts the promotion rule.
- [Is a gift campaign link the same as a prefilled cart link?](https://giftapps.blog/research/campaign-link-versus-cart-permalink/): Treat a gift campaign link and a prefilled cart link as different tools: one can establish offer context while another supplies merchandise, and neither alone proves a valid free-gift order.
- [Why can a gift appear in the cart but be missing from express checkout?](https://giftapps.blog/research/express-checkout-missing-gift/): Trace the exact entry route first: a cart-stage gift may require steps that a product-page accelerated checkout bypasses, so verify the gift line and discount on every supported path.
- [How can you compare cart apps without two systems adding the same gift?](https://giftapps.blog/research/two-apps-adding-same-gift/): Assign one active owner to each reward during evaluation, inventory every system that can mutate the cart and compare candidates separately against the same test contract.
- [How should a cart integration sequence gift updates and drawer refreshes?](https://giftapps.blog/research/sequence-cart-gift-updates/): Give cart changes an explicit sequence: settle the purchase change, reconcile the intended reward, render the resulting state and then allow the checkout handoff.
- [What should a headless Shopify storefront verify before choosing a gift app?](https://giftapps.blog/research/headless-gift-app-evaluation/): A headless storefront needs a documented integration for the reward rule, cart mutations and checkout handoff; a theme widget or generic Shopify compatibility claim is insufficient evidence.
- [Why should gift integrations target cart lines rather than product titles?](https://giftapps.blog/research/gift-cart-line-keys/): Use the current cart’s line identity to target the intended gift; product titles and remembered line keys are unsafe shortcuts when paid and promotional quantities coexist.
- [How should gift labels be checked between the cart and the order?](https://giftapps.blog/research/gift-discount-label-order-review/): Treat a “free gift” label as a message to verify: compare the actual line, quantity and charged amount through cart, checkout and order before relying on the label operationally.
- [What evidence should you collect before escalating a gift-app problem?](https://giftapps.blog/research/gift-app-support-evidence-pack/): Send the smallest reproducible journey with the intended offer rule, actual result and sanitized evidence; distinguish a documented behavior from an observed failure and an untested hypothesis.
- [Why can a gift widget disappear after publishing a new Shopify theme?](https://giftapps.blog/research/gift-widget-after-theme-change/): After a theme change, check app activation and supported widget placement first, then distinguish a missing interface from a missing reward rule and retest the actual cart journey.
- [Why is an automatically added gift still showing a price?](https://giftapps.blog/research/gift-added-but-not-free/): A gift being present does not prove that it is discounted: inspect eligibility, the applied discount and the current cart before changing the product’s catalog price.
