A few years ago when I hurt my back, I couldn't do much of anything, including going grocery shopping, so I used Vons's delivery service a couple of times. They were okay, but fell short in certain areas, like picking old and bruised apples and making substitutions I didn't want, and, oh, yeah, being told that they didn't have what I ordered despite the website indicating that the items were available, but not making any substitutions or even contacting me about it BEFORE the guy showed up at my door.
So if I use a grocery delivery service again, it probably won't be from Vons.
