Here in SoCal.....
Vons is where we do 99% of our grocery shopping, and have for 25 years here, and before that, in norCal, Safeway.
I find the Vons (at least here) to be clean, and the employees friendly.
When I rarely go into an Albertson's or Ralph's, I can't help but not like them. The seem cramped, poorly cared for and stocked, and disorganized. In one local Albertson's, they actually have products sitting up on the very tops of the isle shelves....places normally used for displays and such. There's no way you can grab something from up there unless you're over 6' tall...stupid.
I've tried hard to give business to the local "tree hugger/hippy/natural foods/organic store"(my own name calling) and as much as I want us to eat better in terms of how food is grown, fed, raised, harvested, etc. I just can't get past the rediculous prices and that fact that I'm sure some fat cats who probably own Vons and Albertsons, are sitting and laughing at how much they can gouge the crap out of all the tree huggers and hippies who think they're eating better. $6 for a gallon of RBST free milk, as opposed to the same exact milk for $3 at Vons. That's just BS.
I avoid Trader Joes for the same reasons.....they're just taking advantage of everyone who "thinks" they are eating better by shopping this quaint little trader joe's thing.
I avoid Walmart.....almost at all cost. The problem is, they come in and kill off nearly every other similar store and you're almost forced to buy from them. It's very rare that I set foot in ours. Same with Target, and I never go in Kmart. I just can't stand the bottom feeder, turkish bizzar feel of these places. I don't need a hair blow dryer for $9.97 that was made by someone in a 3rd world country who lives in a cardboard box and earns 1 US dollar a month, while the company makes 100million a year selling blow dryers through Walmart.
That's my story and I'm sticking to it.
