Man...I just got outbid on something I really wanted on ebay

I made a 'conservative' maximum bid (but still well above the bid showing on screen) so my husband wouldn't blow a gasket and I'll be darned if I didn't get outbid by a

sniper in the last few seconds.
Lesson learned......next time the maximum bid will be what I think I should bid and not what I think my husband would think I should bid!
What bidding regrets do you have to share?? I know I can't be the only one whose cryin' in her milk......
