Well, after reading this thread, I spent two hours after work tonight, checking the four wally worlds here in town, luckily at three of the four I spoke with someone who knew exactly what I was talking about and was easy to deal with. I was told they brought the safes in to stores, for holiday sales(not all, but most) and units that didn't sell through the holidays were discounted to $320ish in hopes they would sell them instead of having to return them to the warehouse. If any stores still have one, they're probably in the back of the store. They have been told to take them off the floor to re-use the area for other items, but the price is still honored until they sell or ship back the safe. Apparently they were seasonal, and some particular safe of that price range/quality is brought in each year for the holidays.
Needless to say, I sure wish I knew about this a week or two ago. One of the stores had 5 left in the back two weeks ago, and sold them all between now and then.
Weedsnager, just a shot in the dark here, but do you happen to have a Item Number, or UPC code, or Wal-mart Sku from your purchase? Just talked to another store not as close to me as what I checked in person, and the manager I spoke with said if I had that information, preferably the UPC code, they could check all stores in the region (up to 150 miles) to see if any of the stores show any on hand still.
