I think it would be great if there were tables created for items so when posts are created the item, stats, and prices could be added by the seller which would be huuuuuuge for updating the search functionality.
A suggested example would be a checkbox to use this in your ad, then dropdown selections for the item, probably a couple of filters to get to that item so it’s not an endless scroll, then fields to enter the stats. Then for search a user could choose the item and from similar filters and get all the results versus. Users could put in a price range, etc… I feel like it would make it a lot easier for buyers and sellers to find each other.
