This place is affectionately called Whole Paycheck, but I do the majority of my grocery shopping here and it is quite reasonably priced. I stay with their 365 home brand, don't insist on buying organic (the horror), and usually buy what's on sale.
The key to shopping here is to look at the price tags, since prices change depending on what is in season. Produce here, depending on the item, can actually be cheaper than at Dave's. Pasta can sell for $0.59 or over three dollars for a bag - pretty obvious which one is more budget friendly.
Grocery shopping here is also a pleasant experience in general. The store is clean, people are friendly, fairly spacious, and the food is great. They also have an awesome restaurant/food bar (The Osteria) in the middle of the store itself that offers surprisingly good food at reasonable prices. Appetizers are $5 between 3-6pm - I got four big scallops!
