I am working on a shop for a florist. The bouquets sometimes come in more than one size. I would like to have the different sizes available in a dropdown menu (i.e. regular = £30, medium = £50, large = £70). I would like to set this field up as a custom field rather than a modifier as it applies to almost every bouquet (but not all), and is kind of a pain for my client to have to add themselves into the product entry form (leaves too much margin for error in wording/styling, too). I can set up the entries using a custom Matrix field, but how do I code the template so that Store reads the prices correctly when they're added to the shopping cart?
Thanks!
