I believe TCGBay.com is still up, and operational. This is more of a single card purchase store though. Their prices, last time I checked, are MUCH better than poxbox. Downside? Their stock is on the thin side of things.
Well, I am not sure if PoxBox is the the only one but I think it is great. Maybe prices are not the best but it helps a lot when u need some runes and no one trades them. My thanks to Decondor for all his work. PD: It is normal that he gets some profit for that kind of trades. It is his work and his time, so if u don´t like, shard ur own runes ^_^·
Poxpoints is also up and running (again). No idea if Hugs is around to see your answer to the 1y old question.
