Hi, there is currently no API for getting the discount info for accessories in-game and the :PromptPurchase doesn’t apply the discount for premium users.
Accessories in the catalog can have discounts applied for users who have purchased Roblox Premium membership, however these discounts are not applied if you’re trying to sell accessories through a game/home-store.

Thanks!
