Idk why this happened i tried to buy something that was like 2$ and i have 3$ and i cant buy it cuz this shows up

..AlketFr:

With these other workably good suggestions,

to round them up with this, seems proper:

• Check your Apple ID balance - Apple Support

//support.apple.com/en-us/HT202359

• If your Apple ID balance seems incorrect

• If you plan to delete your Apple ID or change your country or region

• If you have Apple ID balance that you can't use

[Each of these sub-topics offers ideas on what to do.]

First suggestion: 'Get Support ' above-all, is good!

Welcome to the Apple Support Communities.

I suggest you contact Apple Support.
