When you are bidding on something, decide what your bottom dollar is, submit it and walk away. Do NOT watch the auction end. Most of the time, when people get "sniped" - outbid in the last minutes of an auction - they tend to no longer care about the item...it becomes about winning - no matter the cost. To really get the best deals as a buyer, you need to just submit your final offer and let it go. Chances are there will be other similar items. Patience is definitely a virtue on eBay.
"Point of order - I didn't lose ALL the money. There was enough left for this cowbell. [rings it softly and the bell breaks apart in his hands] Damn you, eBay." - Homer Simpson
