U pull ripoff
that's how the game works these days, amigo.
the people at the window don't know their *** from a hole in the ground and just charge for whatever they think that doohickey is. you're at their mercy and they know it.
sometimes you can come out on top, but most of the time you're about even-stevens. also, prices have gone wayyy up. check ebay, offer up and c-list, then evaluate what your time is worth before committing.
