It was a hot topic a while back when SellFire was first introduced as a competitor of Popshops. But I haven't seen much activities of them here lately.
Due to recent "Rakuten acquires PopShops" incident, see Thread: PopShops is now Rakuten PopShops. I'm seriously consider other alternatives in case popshops become LS merchants exclusively.
For those of you who are using or have used SellFire service, would you mind share your experience with them?
