I have 3 items for sale. Two that I want to limit to 1/customer. Right now I'm using Add to Cart, which I like for it's grouped itemization and total owed prior to payment. Even better would be to select any of the 3 items before going to the total owed payment page.
How to do this? (BTW the link from pg 3 of the button set up to Advanced Variables is broken). Thanks.
