You can always wait in line, it might take 20 minutes but hey you get a man/woman taken your cash saying hi. normally the self-check out lady says hi to me when I'm walking out or about to buy whatever.
Every store is going to say join our family, so i don't even see your point, as self-check out also helps cut down on in store prices also. You can shop at Walmart or another store but pay little more its up to you really, just do price matching and see what one is offering the best deals...
Walmart does price matching also, so it might be little hard to get a better deal else were. Only good thing about it is your helping the community out by buying in the mom and pap shops.
