When it comes to OD, each store is different. A "few" items will have "thread" prices, but each store manager decides what the prices will be in their store. None in my area will price match against another store, but they sure want to know "which" store is cutting prices so fast. Sometimes that isn't such a bad question, as last night a store manager let me know a couple other stores in my area that are either closing or cutting back..
Found items
APC surge suppressor power strips 073130400086 mfg. list $89.99 $1.92
3M magic tape 4 packs 5113167014 mfg. list $5.07 $0.22
A couple stores had the security camera stuff half price or better, but nothing I'm into. I did pick up a couple more 3M mouse pads at $0.98, and two game packs at $9.88 each Army Men 4 pack, and Millenium Edition (Civ2, Tomb Raider, Total Annihlation, Duke 3d, and Heavy Gear).
People are clearly buying this stuff up in quantity, as whole sections of "stuff" that I have seen on the clearance table for weeks, suddenly is gone. Btw at the stores with deals, VERY often the employees are openly talking about what they are buying, and the attitude of one of the store managers was that these deals were employee perks.
