I've been successful in getting our last Wegman's to make changes . . . but haven't tried new Wegman's yet to see what the situation there is (likely the pnut bins are in the candy-ish-bin area that is not co-located with produce?).
We won't buy produce at the Quantico commissary -- open bins of nut and peanuts, zero training as to X-contam and the mess . . . just a ZERO as to comprehension!
I shop at the one off 28 in Dulles. I'm not sure where things are put in the Leesburg location (I hate how dark their produce section is there). At the Dulles location, there will be open bins of nuts among the produce (along with candy apples) in late fall through the holiday season. There are bulk bins of nuts with the bulk foods (mostly bulk candy) and in the Dulles location that's at the end of the cookie and popcorn aisles. There's grind-your-own peanut butter station on an end cap in the small, dead-end-like bread section. Not far from the peanut butter machines (about 5 to 6 feet) is a make-your-own trail mix bar. This is what's in the general shopping area and doesn't include the nut-crusted meats in the butcher's counter, the nuts on the brie in the cheese counter, or the items in the hot food section. I think there's also a bulk food section in the organic section of the store.
I still shop at Wegman's because the prices are so much better than my closer Harris Teeter and the quality of meats and until recently the produce was also better. However, I've been miffed at them for how poorly stocked they've been, expired dates on items on the shelves, and no longer carrying items we use.
