My aunt purchased a great little RedBox digital piano for her nephew. Do you guys do repairs on Digital on items like this?

All questions for the retailer should be addressed to them if you want them to be the ones to actually answer your questions.

Did you know questions on this forum are answered by other customers? If you have a question about actual services performed by the store directed towards them you should just call the store and ask them.

No.

I dont think so.
