I’m building a marketplace where there will be only a limited number of products where dif people will sell the same product. (SPMV-Single product multiple vendors)

I’m making a platform to sell LEFTOVER software, Subscriptions, and license.

It is NOT a variable in a single item. 2 sellers, both want to list {software X}, One has 10 months left for 15$ and another 4 months left for 10$. So, HOW to add pricing and expiration date of 2 listings as a single listing.  Like Image, Description and amazon SPMV type price comparison.
