Guys you need to go check out your local KMART.
I'm sure, like always with the Sears corporation it is very YMMV.
I frequent their clearance toys, and they moved a bunch of LEGO sets to their Clearance aisle, (all POTC, DC Heroes sets, the city Marina set). A few weeks back I got the Isla De Muerta set from POTC for about $14.
They only clearanced them a few dollars off, as you can see, but still every penny saved is a penny earned with these little outrageously priced guys.
Anyway, I went there last night and thought I would scope out the clearance toys. I saw a sign saying all clearanced toys, 50% off lowest price.
The legos had been picked clean (including the marina set I had been eyeing which would have been about $18)
I got the Batman and Catwoman set for $5.xx. Only 86 pieces, but not a bad deal at all considering the uniqueness of the set and pieces.
They had 4 or 5 of the same Lego friends set for $5 as well, but having no children, I usually stick to MOC building from certain sets, or buying LEGO on sale.
Anyway, it wouldn't hurt to go check out your local KMART. And if anyone is interested, I could probably get you the Friends set for $5 and would gladly swap it for something of equal value
EDIT: The Friends set is Lego Friends, Andreas Stage, a $15ish set on Amazon (with free shipping). It was clearanced at $10 at KMART, so 50% off would put it around $5.30 after tax is factored in. If you want one of these sets let me know, and I can go and try to pick some up and we can do some swapping
