I decide in advance what I'm willing to pay and if I win, I win. If I lose--it wasn't meant to be. I even do this at the grocery store. No way am I paying $3 for a loaf of bread. Same thing with ice cream. I'm not paying $4 for less than a half gallon of ice cream. Sniper bidders are no different. You have to set a limit and then a bot stays up til 3:00am instead of me.
I'm still determining my limits on the price of gasoline. Knowing that it is cheaper in Missouri than almost anywhere else on the planet helps but it's getting close to the point that my 2 year old Scion may get traded in on a Prius if I can even find one.
