How to Code Exclusivity Into Website?
Here's a tough one:
The project: limit purchases of a product to one person per city per type of service. For example, only one house cleaning service in Boulder, CO can buy the product.
The idea is to keep an area exclusive to the first service provider to buy the product in an area. Almost all services, so no way to count how many. All cities in the USA, with major cities broken down into smaller areas. So at least 200.
Is there a way to code this into a website or payment processor (not PayPal or BrainTree) so that buyer can choose his service and area? And then after his purchase has processed, this service and area are removed, so no longer an available choice?
