Reply #9: Let me explain why those people are utter nitwits:

[Deja Q]

So they don't mind getting junk mail and telemarketing calls from hundreds of fellow companies that Wallyworld sells their database information to?

All walmart needs to know that x amount of Dove soap sold. Then they keep buying it from the supplier because it sold. These twits don't realize that their names need not be included. In fact, if they bought certain types of products, some Homerland Security officials might mistakenly put 1 + 1 together and decide it's 3 because the name of the wallyworld shopper innocently bought all the components necessary to make a cheap bomb when all they did was buy their favorite brands of kitchen and bathroom products, whoopee.) Of course, once they realize that Homeland Security is looking them up, maybe they'll realize that 1984 = 2004.

Also, wallyworld and Sams Club don't always sell the same products as the competition. Will all interested customers write into the company, begging for product x? (many of wallyworld's food products are the plain versions only, nothing exotic. So whatever deals they have with their suppliers only extends so far.)
