You are not alone in your sentiments. I'm a frugal person so I'll always shop there. Why pay double the price for hiking shoes at the trendy sporting store when you can get the same pair at Wal-Mart and have money left over for socks, a garden hose and a couple of extension cords!
But when I go to Wal-Mart, I park in the farthest reaches of the parking lot where my car door won't get dinged by thoughtless welfare moms in their old clunkers and I don't have to jockey for position with the same who actually sit in their idling cars waiting for a parking space close to the door because they don't want to exercise their fat butts any more than they have to in order to stock up on more sweatpants. Which leads me to a personal observation: People who wear sweat pants in public apparently exercise the least.
Im all about being frugal too, but sometimes you get what you pay for.
The last time I bought anything at Walmart was last summer. I bought a pair of Capri style jeans and a cute matching cotton top. I really liked the outfit until after the first time I put them in the washing machine they literally fell apart at the seams (and I did following the laundry instructions).
I thought the outfit was so cute and quite a bargain when I bought it, but considering I only got to wear it twice, it turned out to be relatively expensive.
