I think one of the key areas that almost no one else can touch (maybe Wegmans) is in the area of prepared items - good, big selection, and expensive! I bet their internal numbers show massive profit in this area. Try going to one at lunchtime (just did in Boston Beacon Hill - incredible traffic with around 20 cashiers going full tilt).
Organic is becoming more of a commonplace offering.
"You can buy organic at your local supermarket at better prices"
MUCH easier said than done.
Please note that price is just one component of COST.
I don't buy a lot of ORGANIC food. In my hood, WFM consistently offers the best QUALITY produce, then Stop & Shop and closing out the rear in a DISTANT thrid place is Shaws.
Let's talk (again) about apples. I bought four Macs at WFM on Sat @ 1.99/lb. Next day I went to Shaws (since I have only consumed half a cup of the kool aid, I don't exclusively shop at WFM). I bought two Macs @ 1.89/lb; yup a WHOPPIING 10 cents a pound cheaper than WFM. But...the texture and taste of the WFM Mac are superior to Shaws' Macs. Bottom line, regardless of price, I rarely buy produce at Shaws, since experience has shown that Shaws procduce is inferior. You want to talk about Shaws' organice offerings? They are AWFUL. Sometimes (in this case just about EVERY TIME) I get what I pay for.
"you can also buy good organic meat at your local supermarket at better prices"
Why settle for "good" when you can get excellent at WFM? I've yet to see grass fed (you know, the food cattle used to consume before The Man determined corn was a "better" feed) beef at either Shaws or S & S.
