That's probably because (As was alluded to in other threads on HN), most of the price cuts came to low-turnover specialty goods. The $8 bottle of lavender water is now $6.
I used to shop at Whole Foods regularly back when they were Fresh Fields in the mid to late 90s. Now I find them just too expensive. Maybe it's just me, because back then, I was feeding a couple of toddlers and now I'm feeding several large eating machines.
Canned beans were already pretty competitive, don't think any dried ones changed. No change on onions, leeks, beets, pork, or bread that I noticed. Tilapia went down by a couple bucks a pound.
