There are three souvenir/gift shops in Hell, and all of them carry similar items: Most people who come here don't want to leave without at least some small memento or maybe a T-shirt that says "I've been to Hell and Back."
We bought postcards - some of which were mailed next door at the Hell Post Office for it's unique postmark. And of course, I got a refrigerator magnet for my collection. I also bought a Coke which I enjoyed by adding a bag of salted peanuts. Putting peanuts into your Coca-Cola is a tradition among many folks in the southern United States. Here in Hell, Cayman Islands, I found the treat to be just as refreshing as it is in Georgia.
As to be expected, Hell's gift shop is full of Hellish items. Shirts, hats, bumper stickers, postcards-- all with either the Devil on them, and/or witty Hell captions such as "Wish you were in Hell."
Dumb yet amusing.
What to buy: Definately buy a postcard and have it sent from Hell.
