Not at all, you can B2M anything that's eligible, regardless of how you got it, or even what country it's from.
I've looked through a dozen or so of the pages in this thread, as well as the FAQ and can't seem to find the answer to my question.
I have a lot of empties that family and friends have sent over from England and America and others that I've purchased off ACW, so would I be able to B2M these at my counter in New Zealand? I've purchased a few things from the Wellington counter and I've noticed that they actually have your name and everything you have purchased in a folder, so I'm worried that I'll only be able to B2M what they KNOW I have bought from their counter.. Could any other Kiwi's or MUAs help? I have multiple items and would love to exchange them for a few lippies.
Thanks in advance!
