Will my iTunes codes work with the uk store? UK resident needed for experiment.

I have a few iTunes codes i got from a promotion and I was wondering if they’d work in the UK iTunes store. If anyone here is a UK resident and wants to help me find out, let me know and I’ll give you one so you can test it for me. My aim handle is gozulin.

Your help shall be appreciated.

I just found out they don’t work. Please ignore this post.
