When montgomery ward closed down years back all their customers were sol because they backed the warranties.
Actually, Montgomery Ward and Service Merchandise were both online only web retailers the last time I checked, but they were BOTH still in business.
Any clearance sales will probably be run by scammy liquidators which means the prices would be jacked up from the current instore prices and worse than online prices so I am not betting on any sales here.
Thus far, I've been to store closings for Kmart, Sam Goody, Toys R Us and even a couple of CompUSA stores and while I agree, the prices usually are jacked back up to MSRP for each item.
Of course, most NORMAL consumers think that 20-30% off of MSRP is a phenomenal deal and they'll rush in at those percentages and clean the place out of anything GOOD.
Mind you, about 3 or so years ago when Transworld bought Sam Goody, it took forever for their store in Paramus, NJ to empty out and on one of the final days of business they still had some old PS1 games that were worth a good buck.
But unfortunately I was just as broke then as I am now sometimes.
CompUSA isn't completely out of business though, since I believe they were bought out by Systemax or one of those online only PC sites.
