The majority of ebay users have already switched cause it was required to do so, same for me, here's what i was sent and this was 3-4 months after my buddy told me about it, so it took a bit to get to me, not sure how they're doing it in what order but I've switched, already saved me around 50% on my fees, I have no complaints:
