“What do I do first?”

1. Open Home. Under “Suggested test carts, from your discounts” are up to five carts: the two discounts most likely to clash, your newest code, a cart just under free shipping, and your automatic discounts.
2. Click Try it on one. The Simulator opens with that cart and calculates it at once: the price X-ray, and a sentence for every discount that wasn’t applied.
3. Back on Home, Add all as test carts saves the suggestions you want checked. Each one is priced and then checked on your plan’s schedule. Nothing is saved until you choose.
4. On Pro and Business, open Settings and check Send alerts to, so changes reach the right inbox.

• Re-run all and Calculate a cart, and the counters: Test carts, OK, Changed, Last check.
• Your first five test carts, changed ones first, each with its total and a small price X-ray.
• What we found in your store: active and scheduled discounts, apps that create discounts, shipping profiles, markets and combination problems. A shipping app that no shipping zone uses is flagged here too.
• Recent activity: store changes, and each round of checks (“Daily check: 2 carts, all OK”).

The app’s pages, in the Shopify admin’s menu: Simulator (price any cart), Test carts, Discounts (every discount with what it combines with), Combinations, Refunds (Refund Watch), Plans and Settings.
