How can I create a useable URL that I can use to link to, from a "Buy" button on my ebook reseller website in order to display 3 product choices on a single product/ store page (it needs to be a store page in order to make sure the show cart only on store page works correctly).
For example I have 3 different product items setup for each book I am selling. The 3 product item choices are: Print format, Digital format (ebook) product, and the Print/Digital format Combo package. At first I had created a single Product page for each book with 3 different variations (print, ebook, and print/ebook combo) and this worked great because it was a single product page with variations with a URL that I could send the "Buy" button to. Well, this didn't work since the support group stated that a digital and non-digital product variation cannot exist within a single product (see a previous question post from me), so the functionality was broken using it this way. They instructed me to create 3 separate products for each of the formats of each book rather than using the variations. As I started creating these different products for each book I was trying to find out "How will I send a single "Buy" button to send me to a page that will allow me to choose between the 3 different products. I do not see a useful shortcode to accomplish this, and even if there were a shortcode - how could I send the "Buy" button to a shortcode instead of a URL? PLEASE HELP!!
