I flew the coop (technically, I took the ferry) to delightful Vaxholm. If you're not busy with…read moreoutdoor sports, it's a great place to amble around, fortified by ice cream, gelato, and baked goods from the various little shops.
Wander a wee bit father from the port and you'll encounter this wee version of a Coop grocery store. Compact, but they make good use of the limited space available. You can certainly find all the basics; really, you'll like find everything you need.
The only real minus was that some of the fruits and vegetables weren't too fresh. The strawberries i bought looked good but looks were deceiving; they were already starting to rot the next day. They had a little vegetable bar and a huge selection of drinks. Prices are average.
Turn right when you come out of the store and walk a few minutes straight down, and you'll find yourself at the port. Turn right out of the store and turn right again immediately, you'll find a hill. At the bottom of that hill is the bus stop back to Stockholm. (You'll have to switch to the Metro at the line's end to get back to the center of town.)
