Irony
Vending machines selling: beer, batteries, newspapers, cut flowers, or used school girls panties, but NO SNACK FOOD. 
Seaweed flavored potato chips.
No point being ripping. 
Walkers are bad, bad boys 'cause they changed the colour-coding of packets. Back in my day blue was S&V, not C&O.
And of course don’t get me started on those Lineker adverts…
And my friend reminds me: we are unlikely to find a certain Osama bin Laden in the States.
This actually happens in real life? I always assumed it was an urban myth.
TimTams. And Freddo Frogs. And Caramello Koalas.
Correct me if I’m wrong. It will make me a lot less apprehensive about my next trip to the USA (whenever that might be).
And that’s a bad thing because. . .? 
Though I’d admit I’d love to have a Citroen DX.
How about good Haribo gummy bears? The ones they sell in the States are pale imitations of the bliss that is the stuff my uncle’s BIL ships over from Germany.
Proper rashers, underage drinking in bars, doner kebabs, decent butter, boobies on telly (thanks, Coldfire), bad teeth and foreign news.
Still, they’ve got loads of stuff I’d like and the doner kebabs are only a hunch.
Huh? It may be pasteurized, but it’s definitely not UHT. That stuff’s not at all popular here, at least not compared to a normal carton of milk.
I think they have doner kebabs there, but they call them giros or something.
The metric system! and a population that thinks walking to work is normal.
What’s UHT?
Well there’s still something not right about it. There are three ingredients in tea; team water and milk (and sugar if you’re a builder).
If the tea and the water are the same it must be the milk. It doesn’t taste like fresh milk.
FWIW we Brits are hopeless at coffee.
Mmmmm, team water.
Milk in tea? Ye Gads, I’ve never been able to understand that! To me, proper tea is tea leaves (preferably loose, but bagged if that’s all available) and water. That’s it. Tea shouldn’t be bitter (that’s oversteeped), so you shouldn’t need sugar.
And I don’t care who likes it, Lipton tea makes me literally sick to my stomach each time I try it. I feel nauseous for quite a while afterwards.
Considering your British cuisine cookbooks are world-wide bestsellers, too, I’m not surprised.
You can get Haribo Gummy Bears in the US. Granted, they aren’t on the shelf of every candy carrying store, but you can find them. My ex-FIL used to buy them in bulk at Price Club(Costco).

Kaiten-zushi (A type of sushi place where plates of sushi go by on a conveyor belt and you take what you want). Vending machines that sell beer (and sometimes sake, whisky, etc.). Green tea ice cream. Shrimp Katsu Burgers. The list could be endless…
YAOI and most shoujo manga.
You can get it in German. You can get it in French. But you can’t it in English.
'course, being in la belle province, I have access to all the trashy Japanese comics I’ll never need
OK, you’re wrong. All three are available here. Go to the confectionary section, and you will find them.
I think most of the things on this list are available, with today’s modern shipping practices and the number of expats living in the U.S. who want what they used to eat “back home”.
The main drawback is the price. I can get Mexican Coca-Cola made with real sugar here in Cleveland if I don’t mind paying an arm and a leg to have it shipped here.
There are some items that are unavailable due to import restrictions, I think most unpasteurized cheeses fall into this category.
Havana Club rum, aged 7 years. Ahhh!
(produced of course, in that great threat to freedom, Cuba)
