OK, so I know I have mentioned Fenwicks a few times, but just so everyone knows, here are the American imports at the Newcastle location, so if there is a location near you, it's worth checking out:
Hershey bars (even Cookies and Cream and Mr. Goodbar!)
Watchamacallit
Hershey Kisses (also Hugs and Kissables)
Reese's Pieces, Nutrageous, Peanut Butter Cups, Big Peanut Butter Cups, and Reese's Puffs cereal
Dark Chocolate and Peanut Butter M & Ms
Lucky Charms cereal
A-1 steak sauce
Miracle Whip
Skippy Honey Nut Peanut Butter (creamy and super chunk)
Regular Skippy Peanut Butter
Double Stuft Oreos
Chocolate Creme Oreos
and a few other things I can't remember!
Here is their website for a list of locations:

Be aware that a few of these items are very expensive, though! A box of Lucky Charms was an astonishing £7 (ditto for the A-1)! But the Skippy, Oreos, and miscellaneous candy bars weren't too bad. Anyway, you can look at it as a special treat if you do decide to splurge. For me, it's the comfort of knowing they're there.
