I love Wegmans, but I mostly shop at Price Chopper which also happens to be the closest grocery store to me. I do occasionally stop by Hannaford's, Shaw's, Stop & Shop if they are on my way already (prefer Shaw's out of the three of them, the one on the Watertown/Cambridge border is great), but I found Market Basket disappointing on my first and only visit there. Trader Joe's and Aldi's are more for something specific only they carry. Whole Foods only if a friend who is a big fan drags me in there.

I tend to shop by what I like instead of going by price, though...
