Connect with a merchant that will issue tokens for their stores. The tokens are bought at discount. So, let’s say each token at the store is worth $1. Online, you can buy the discount tokens for example at $0.90 (10% saving), and spend them in that store or store chain only.
Let’s call this DT (Discount Tokens)
Make an Aepp that can create DT’s for a particular merchants account. And that merchant can sell those DT’s at discount to customers for purchases in their store only in the future. But create a way where the DT token can have multiple merchants issuing their own tokens under the DT token (kind of like a token within a token). That way, you don’t have to make a whole new token for each merchant - unless that is easier to do somehow.
