Bartel's has been a local chain drugstore since the 1890's, and I'm really surprised that there wasn't already a listing for it here on this site. Bartell's carries much the same items as RiteAid or Walgreens, but they're owned and operated by a local company, not one headquartered back east somewhere.
Bartell's has an intimate, friendly, local feel to it. They have a good pharmacy also. Sometimes they carry something long after some of the other stores have stopped carrying it, which comes in very handy if you're looking everywhere for that item! Their prices are reasonable too.
