No "bag o' crap" yet again! Curses to the woot-off!

I happened to be obsessively refreshing www.woot.com and there it was....the elusive "bag of crap" which is a package filled with mystery items that hopefully includes some expensive electronic gadget... for only one dollar plus $5 shipping. The plan is to buy the max of three items, hence pay only $8 for 3 mystery packages. I hit "I want one" and...the server is unavailable! How do they sell 4500 "BOCs" in like 7 seconds???
