Why this category prices the way it does
Dairy is the most regionally stable category — milk and eggs track USDA market reports closely, so the price gap between services is usually under 25%.
Boston grocery context
Boston's grocery scene is shaped by the local Stop & Shop (Ahold Delhaize), Star Market (Albertsons), Market Basket (cult favorite, not on Instacart), and Roche Bros. Wegmans has multiple Boston-area stores (Newton, Burlington, Medford) with strong local following. Aldi has dense MA coverage. Whole Foods has multiple Boston and Cambridge locations. The metro's narrow streets and college-density mean delivery vehicles often double-park briefly — building access varies hugely between Back Bay brownstones and South End apartments.
Boston shoppers consistently get the best value from Instacart-Aldi for staples. Add Wegmans-via-Instacart for produce and prepared foods — the Newton and Medford stores have wide same-day windows. For Cambridge and Somerville, Trader Joe's is the cheapest premium fill-in option.

Service fees, delivery, and tip all depend on basket size — the cheapest per-item service isn't always the cheapest overall.
