A store for expats

If I were to open a store here, it would be one catering towards the unique tastes of expats that aren't satisfied by London's retail network.

For Americans I'd start by stocking:

Marshmellows
Trix/Apple Jacks/Corn Chex
Stendig Calendars
Apple Sauce
Apple Butter
Travel-sized toothpaste
Travel-sized deodorant

And Mexican food, single slices of pizza and hamburgers would be made available to shoppers at all times.
