Well, I recently asked Celga to place a bid for me for the first time. I was in a bit of a jam last night because I came across an item I wanted to bid on, but the auction was going to end in less than 9 hours. After considering my options (Rinkya has automatic bidding, but it's really expensive, and Shopping Mall Japan has competitive pricing, but I'm 99% sure they wouldn't have raised my bid limit in time to bid), I decided to try out Celga. I knew that there was no guarantee they would bid in time, but I thought it was worth a shot. And guess what?! They got the bid in! I wouldn't have held it against Celga if they weren't able to bid in time, but they were able to. Yay So...so far, so good (great actually). I'll continue the review once the item is in hand.
Yeah the celga folks have always given me pretty much the best service I could ask for, very nice and quicker than I anticipate I have never used any of the other bidding services though, so I don't know how they stack up
