I only ever just bid my highest bid and then walk away. I'm not about to pay a ridiculous price, some other sucker can take the fall.
I do the same. I sniped once or twice in my younger years, but now, I learned that if I really put in a "fair" amount for a maximum bid and walk away, it's highly unlikely that a sniper will take the auction away from me (In fact, it's NEVER happened to me yet). Snipers only seem to try their hand at it if the auction is only quite below fair market value.
What really PO's me about Ebay is when some seller tries to stick it to me with absurd shipping charges. Case in point: I won an auction for a Turbo Extension Cable for $9.99 a couple days ago, but when I get the bill from the seller, he's tacked on $16.84 shipping! I live in Canada, not the South Pole!
Yeah, I friggin hate that crap too! And I ranted about this on another thread before, but what's even worse is that those goddamn couriers charge you for "brokerage fees". It's already a slap in the face that you have to pay these at all, but when you pay a $20 fee for a $1.50 duty on a $25 item, after you paid another $20 for shipping, you just wanna scream - ugh!
