Northern CA shopper here. Never - and I mean NEVER - shop at WM. Just a personal choice. Target and Dollar Stores also sell groceries but we avoid those also.
I have 80% of our groceries delivered from our supermarket of choice. We are club members and receive the relevant discounts on-line. Each item lists all coupons available, so if there's multiple ones you can take advantage of any or all. The yearly cost is $98 and since I order 3-4x per month it saves me money, time and gas.
We are very brand-specific so I DO NOT like substitutions, which is the only negative about delivery. However, I'm an experienced cook so the old "if life gives you lemons, etc.etc." just requires some creativity [smile]. Grocery delivery does have the disadvantage of plastic bags, but they're easily recycled. Every large grocery must, by state law, accept clean plastic bags for recycling.
The company's website is a little clunky but very clear and easy to set up specific date/time for delivery. I believe the fastest delivery is 4 hrs but I'm usually scheduling mine 3-4 days in advance so I don't pay much attention to it. I get the 1-hr window so I'm not waiting around all day. Works great, no issues at all for the last two years.
As we are also Amazon Prime members I can get free delivery, no minimum, within 2 hrs from Whole Foods. Used it once in an emergency and it worked like a charm, saved my holiday baking!
There is also an upscale on-line only service that offers locally vendored foods only. Excellent meat, seafood, cheeses, produce (it's a reliable source for Tokyo turnips, one of our winter favorites); also a wider variety of products from local producers I don't always see in the stores.
We love sausages, for example. Although everybody carries andouille and linguica and bratwurst, not everyone carries the more unusual sausages, such as merguez or a pork with turmeric and pineapple. The on-line service is wonderful for that. $65 minimum for free delivery.
We also belong to a produce CSA - there are many here. This one specializes in organic produce, and contracts with growers/vendors for produce that is perfectly good but does not meet the "cosmetic standards" that grocery shoppers insist on. They also contract for excess produce. You can have deliveries once a week or once a month; I get ours twice a month which works out perfectly for two people. Also $65 minimum for delivery, but their delivery charge is only $5.95 anyway.
I use it as a supplement, not a replacement, for the regular grocery deliveries. I have toyed with the idea of a butcher CSA but I think we'll probably stick with two local independents: one a specialty butcher and one a single-store upscale with an outstanding meat and gourmet cheese depts.
Since we're in a large city we have an excellent and large choice of markets within 10 miles. Four major supermarket chains, Trader Joe's, Costco. Nearby we also have a full-size, full-service Mexican supermarket (butcher/seafood, pastry/bakery, massive deli, fresh produce). There's an Asian supermarket chain with stores all over the state (3 near us), with those same departments except an Asian focus (Chinese, Japanese, SE Asian).
Smaller markets include one large-store local chain and one small-store local chain who offer all the standard good but both specialize in the best and widest variety of produce, organic whenever possible. Both are favorites with local chefs like Alice Waters (of Chez Panisse/Berkeley).
Tons of small independent shops: Indian, Halal, Himalayan, Ethiopian, Eastern European, Scandinavian. Also some very good bakeries and specialty delis.
Being retired we are running errands 2-3x/week, so that's when we stop in at the medium- and smaller-sized markets for specialty items.
