I have always boasted of my great buys; so it is only fair to mention a screw up. Maybe someone can learn from it.
I bought a set of reconditioned Dewalt 36v tools on Ebay for $480. That is $75 less than I could find them for anywhere else. There was a packing slip on the box. The seller had bought them from Amazon two weeks earlier for $399! I checked Amazon today, and they have them for $399. ARRRGGGHHH!
Well, they didn't have them when I checked, and I sure don't need them now; but they are great tools, so if anyone wants a good buy...
But you know, they are going for over $500 right now on Ebay, maybe if I bought a few sets... nah; ain't worth the hassle for a $25 profit. (freight, ebay expense, paypal expense...)
