Actually Celga is pretty good about bidding, in 
all likelihood your bid wasn't high enough to 
begin with. The highest and earliest bids get 
priority. Next time when you ask them to bid give 
them you max highest, especially since they bid 
when the auction usually draws to a close there 
is seldom a chance to increase your bid. As for 
the silent auction, its quite possible you can 
win that auction if you bid high enough. It 
wouldn't hurt to try, right? Good luck.
