iTunes account

I didn't know where to contact iTunes so i thought i would you guys
Can i use more than one iTunes acount on my iPod? Ive been given my aunts iTunes account because she is getting rid of her computer and will have no reason to use it. so is there a way that i can buy coins or something using her account so it goes onto my ipod? or with songs would it delete my songs because they arent part of my library but hers?
any help is much appreciated

Go to Settings - App Store, sign out of your account and sign in using hers, you can use your account to make purchases provided you have the proper verification.

It won't overwrite anything in your iPod, the profile that you sync your device to are the ones on iTunes on your PC.

Yeah there really shouldn't be any issues if you follow what backburner says.

Cool, thanks very much guys

ive done that micho (different circumstances) but when i transfered itunes accounts and tried to buy coins with the one it wouldnt let me to have it work i belive you need to delete haypi and re-download it on your aunts account
