It often happens to certain users who tend to buy Robux, or don’t have it due to their account location. Some of my friends and family members had Robux deposited and then had it removed Regional prices
Hi, thank you for reaching out. For purposes of Regional Pricing, economic location is not always the same as account location. To determine a user’s economic location, Roblox looks at signals, including VPN usage, billing history, and account history. If their economic location can’t be determined, users see the default global price for the item instead.
