avatar store-props (free/paid)

ok, say i buy a used xbox 360. i can get a free/paid avatar prop with it and transfer it to my xbox one, right? how would i do this? i assume the xbox 360 would have to be connected to the internet which means i'd have to disconnect my xbox one from the
internet and connect the 360 to the 'net. after i get the prop onto the 360 how do i get it onto the xbox one? also, during transfer do the 360 and xbox one both need to be connected to the 'net or just one or the other? not sure if i'd be able to have 2 consoles
connected to the internet at the same time.

As I stated before, you can use currency from an Xbox gift card to purchase avatar items only if you're purchasing them from a 360 console. If you're making the purchase on a One or the website, you need either a credit card or Paypal on file as a valid
payment option.

If the system won't accept your ATM card, then it can't be used as a valid payment option. If it does, then yes, you would need money in your account in order to purchase paid for items.

I'm not sure how bank accounts can be used or if they can be used to purchase avatar items. That may not be a valid payment option for avatar items.

These are community forums so most of us here, including myself, are regular gamers like yourself.

i'm upset. i put in the 16 digit card #, no spaces. i tried the 3 digit verification # on the back and 4 digit on the front . i've no idea what i'm doing wrong. i really hate calling xbox support.

one thing: when it asks for the exp. date what do i put for the date? i only know the month & year.

not sure how i'd pay for any charge. i can only pay for things with a money order. so you're saying i should enter 5/18/2016 as the exp. date? i don't how it could be the exp. date. any idea how long all of this'll take me to complete?
