Just between you and I, I'd forgo going just to avoid the old people who shop there.
I suppose I should just be glad they don't have that sourpuss old guy working in the electronics like they did 5-10 years ago, actually it may have been longer as he would scowl when kids wanted to buy a worm light for the gameboy color etc.., I remember trying to buy a memory card for the PS1 there and he was very reluctant to sell it to me. He obviously knew nothing about electronics whatsoever and obviously didn't want people buying electronics because they are evil or something.. There are basically no old people anyways if you go on the weekend, so go on Sunday, the old people don't come out till during the week. Nothing against old people btw, but its odd that kmart attracts such a concentration of them.
Maybe I should be a jerk and return my copy of 3D dot heroes that I have not played or opened yet and then go and buy another one right there for the 25% off.
