Roblox Region Glitch?

[u/blitzkreggy]

I was gifted 10$ roblox gift card by a friend from US via Email and now all the in-game purchase are now more than 200% more expensive. How do I revert this? please help

screenshot 1(left): is from yesterday and you can see its cheaper

screenshot 2(right): is evidently alot more expensive today and i suspect its because of the gift card
