Summary
Once a design is in your Cart, each line item has Quantity
controls, an Edit design button, and a ⋯ menu with Duplicate
and Remove. Quantity and pricing update live and correctly.
Duplicate and Remove work correctly. Edit design does not —
see Warnings and limits.
Use it when
- Use Duplicate to add a second copy of a cart line item as its own separate entry (for example, to set a different quantity or edit it independently later).
- Use Quantity to change how many copies of a line item you're ordering.
- Use Remove to take a line item out of the cart entirely.
Before you begin
Have at least one design added to your cart — see Proof links, cart, and checkout for how to get there.
Steps
- Go to Cart.
- Select + or − next to a line item's Quantity to change how many copies you're ordering.
- Open the
⋯menu on a line item and select Duplicate to add a copy of it as a new, separate line item. - Open the
⋯menu and select Remove to delete that line item from the cart.
What changes
- Quantity changes the line item's total using the stated per-item
pricing (
$50.00 first copy · $25.00 each additional) — confirmed directly: increasing quantity from 1 to 2 changed a line total from $50.00 to $75.00 exactly, and the cart's Merchandise and Order total updated to match. - Duplicate adds a new line item named after the original with a
— copysuffix (e.g.Classic square #1 — copy), at the same price, confirmed to correctly increase Merchandise by the duplicated item's price. - Remove deletes the line item and the cart briefly shows a

Print note
Not applicable — cart quantity, duplication, and removal only affect what you're ordering, not any exported file.
Warnings and limits
- "Edit design" does not work. Selecting it navigates to
/editor, a route that doesn't exist (the page title readsPage not found), and it does not load the cart item's design back into the editor — the artboard comes up completely empty (No layers yet). Reproduced twice, independently. Filed as issue #51. Until this is fixed, if you need to adjust a design that's already in your cart, rebuild it from your original file, a proof link, or an exported copy — don't rely on Edit design to bring it back. - "Reorder past creations", described in the app's own marketing copy, requires order history from a completed order. This was not tested — completing an actual purchase is outside the scope of this research. Treat reordering past orders as Needs product confirmation.

Desktop and mobile
Quantity, the ⋯ menu (Duplicate/Remove), and Edit
design were all confirmed present and reachable on both desktop and
mobile — the Edit design issue was found on desktop; it was not
independently re-tested on mobile, but there is no reason to expect the
underlying routing bug to differ by viewport.
Troubleshooting
| Symptom | Likely cause | Recovery |
|---|---|---|
| Edit design shows a "Page not found" title and an empty editor | A confirmed, reproduced bug as of this verification date (issue #51) | Don't rely on it — rebuild the design instead of trying to resume it from the cart |
| Cart total looks wrong right after removing an item | The cart briefly shows a transitional state while re-verifying | Wait a moment for Cart verified and prices are current. before checking totals |
| A duplicated item has the same name as the original | Expected — it's suffixed — copy to distinguish it |
Check the full line item name, not just the format |
