Re brand-name appliances sold at Wal-Mart
Here is some info that may be interesting or useful for those considering buying any kitchen appliances at Wal-Mart.
In brief: some manufacturers sell appliances that may be manufactured specifically to Wal Mart's specs, under the same make and model number as those appliances sold at other retailers.
In the past, I've heard allegations that other leading retailers of consumer products did this, and that the custom-made products actually had construction or components that differed from the ones sold elsewhere. I have no idea if this is the case with Wal-Mart.
I learned about the custom manufacturing for Wal-Mart via a close reading of the consumer instruction manual that came with a product I bought (and subsequently returned).
I'm not sure if this applies to Wal-Mart, but a long time ago when small appliances were made in the USA, Proctor Silex made toasters for K-Mart, Sears, and many others to store brands. In most cases the end panels were different but the internals were the same. I've also heard that some manufactures make items to two sets of specifications, looser for some retailers, again, don't know if that's the case with Wal-Mart.
