Sorry to hear that - really poor on their part. I swear they have an army of trolls working as customer service.
Does it make you wonder if it might be NA-ers trying to force you off so they can charge more for theirs??
I honestly think it is a competitor or two who did this. A lot of the items I sold were always listed at $20...although this may seem high to some folks as an "1 cart" basis, by the time I figured in eBay and paypal fees, shipping costs (I always included free shipping), actual cost of the item for me, etc, I was making very little profit, from $5 - $10. I just sell things to make a few extra dollars for my own collecting goals, but to also help people get these items for prices that aren't as inflated. Because of this, I think a few sellers probably got angry at me, for stealing some sales from them. Oh well.
I don't think things will get resolved, so if they don't, I'll post a more detailed selling thread next week.
