Are you miles from your home across the pond and have an aching in your heart for scones, snowballs, or jelly (which those silly Americans call "jell-o"?)
Just drive across the bridge to Mt. Pleasant there ye shall find a whole treasure trove of honest-to-goodness UK import foods and gifts.
The prices are a bit high, but certainly cheaper than taking a flight there and back, right?
And you'll be right at home with the staff. I don't know if they're all british, but at least they fake the accents well :)
