How is the list total worked out? Quantity × price for each item that has a price. Items without a price count toward progress but not the total.
Can I reuse a list? Open the list, tap the ⋯ button and choose “Uncheck all items”.
What does “Log picked items as a purchase” do? It opens a new purchase entry with the total of the checked items filled in, so the trip shows up in your spending.
Compare
How are offers ranked? Shelf price plus shipping, minus any coupon, divided by the total quantity (size per pack × packs). The lowest price per unit comes first.
Why must every offer use the same unit? A price per ounce cannot be compared with a price per gram. Use Guide → Unit Converter to convert sizes first.
Purchases
When does the return countdown end? On the purchase date plus the number of days you entered. Some sellers count from delivery instead — enter the date that matches their terms.
I am not getting reminders. Check that the reminder switch is on for that purchase, that it has a return window, and that notifications are allowed for SingleStorc in the Settings app.
Why did my total drop after a return? Purchases marked as returned stay in the log but are left out of spending totals.
