We have a situation where we want to limit products on our page to only order 1 time and one time only per customer (even across multiple orders). We have ShopSite Pro v12. We have looked into using coupons that were one time only, but that doesn't give us a way to limit additional purchases of the same product. The end result should be that the customer can only order the product one time, and all future orders by this customer for the same product would be rejected.
Any help or direction would be appreciated.
