Context:
In the Furry Hideout we have 3 supporter tiers Supporter, VIP and Super Supporter. These are offered as Subscription and as a Temp Listing (30 days) to allow users to gift it to each other since subscriptions don't support that.
Today we had a user complain to us that they first bought the subscription and then the temp listing as it's 100 credit cheaper (since you wont get the group role) and they tought it would be a discount.
Issue:
Buying a subscription wont prevent you from buying a listing that contains the same products.
Reproduction Steps:
  1. Go to the Furry Hideout VRChat World.
  2. Buy the 500 Credit "Supporter" Subscription in the store.
  3. Buy the 400 Credit "Supporter" Temp Listing right next to it.
Expected Behaviour:
If a user already owns all products of a listing through a subscription they should not be able to buy the listing, or at least show them a warning message about it.
