somehow i doubt you measure or collect any type of data that would allow you to come to the conclusion that your local walmart is doing alright. i wouldn't call eyeballing the amount of cars in the parking lot scientific and if walmart internal staff are sounding the alarms, most would be inclined to listen to them over some permabull pumper.
If you did, you notice the problem. Walmart can;t survive with a few hundred shoppers on a Saturday. They need ten's of thousands per store to even break even, i assure people are not logging on to Amazon either.
I dunno, I just gor back in from being out, its a zoo out there.... Regarding AMZN, the over priced pig, well I just got off zappos so I think you're wrong. Like I said, Walmart seemed no different to me
