Believe me, when the Wal-Mart Supercenters in Sacramento County, CA starts opening (the first one in Citrus Heights, the second one in Elk Grove), they will take away a LOT of business from supermarkets nearby (well, unless you're a place like WinCo, which is essentially an oversized supermarket with enormous buying clout).
Wow. Just goes to show how different peoples' experiences can be. I never heard of Albertsons until I came to Seattle. I don't have a car, they have an online shopping service - I've been a loyal customer for the past 4.5 years.
Whether it's the delivery service or the in-store staff, I've had nothing but positive experiences w/them. Even when I've had a problem, it's been resolved curteously and always in my favor.
Coming from the DC area, the prices didn't seem expensive to me, so I can't complain about those, either.
