When Add asks the shopper to choose

Add opens a sheet on every product: the photo, the price, and any size, colour or weight to choose. Nothing is bagged until they press Add to bag.

There is one Add on the shelf and it always opens the same sheet. The sheet is a preview: the photograph at full size, the price, what is left, the description, and the sizes, colours or amounts if the product has any. Nothing sits in the bag until they press Add to bag on it, so it is one tap to look and two to buy.

A Retriever storefront as customers see it — Every Add on the shelf opens the same sheet.

What counts as a choice

Retriever only knows what you filed on the product: sizes and colours, or sold by weight. A line in the description that says steamed or fried is not a choice until you add it as a size. Notes and blurbs never open the sheet.

What the shopper does

Plain item. Add opens the sheet on the photograph and the price. Add to bag on the sheet puts it in the bag, and the floating bar then says View bag, which only opens the bag.
Item with a choice. Add opens a sheet from the bottom of the phone, with the same chips the product page uses. They pick, then press Add to bag.
The card itself. Tapping the name or the picture still opens the product page. See details on the sheet goes there too.

The Add sheet open on a phone: a photo of House Latte beside its name, the category Coffee, NPR 190, a one-line description, See details, a minus one plus stepper, and Save beside a black Add to bag button — The sheet on a plain item in an example shop. It is a preview until Add to bag is pressed.

At a table the sheet does not change the address, so the table code stays. Sending to the kitchen is still the bag's own button, see table ordering.
