I find them to be the same as anybody else, some sections of the store are ruled by imports, some aren't. Small appliances and textiles are totally import happy, tools run more even, entertainment is still mostly printed in the US (and usually loads cheaper at Wally, CDs software and DVDs are probably where 90% of my Wally dollars go), pet supplies are pretty wide open. Wally's got the same stuff as everybody else, well not the same stuff since they're a discount retailer and not everybody else is, but the most of the same brands and a similar spread of places of origin for their goods. I'm not into the superstore idea for groceries, I don't like they're grocery selection usually so I avoid them (I'm a total snob about most of what I eat, and an absolute snob when it comes to my alchohol) and know nothing more about that selection than it disappointed me when I first looked.
The retail world today is import happy, maybe that's a bad thing, doesn't really bother me that much, but I just don't see Wally importing any higher percentage of their goods than anybody else. As the number 1 retailer in the world they, of course, import more goods than anybody else, but having worked in retail in my past I think in shelf space, and as far as shelf space is concerned they're just another retailer that imports stuff.
Oh, I know, I'm not happy with any other retailers either. My only beef specifically with Wally on this issue is that since they have so much more power to move the market singlehandedly than does anyone else, that they should be held to a little bit higher standard.
