<human>: Can you summarize the given text in a few sentences?

My wife and I were talking about how we really missed Paprika and Cheese and Onion Pringles from when we visited Europe, and had the crazy idea that people from Europe might feel the same about stuff from the United States. However, no one wants to pay the ridiculous prices from the e-retailers that will ship it to you.

So here's the idea:  People post stuff they miss that could easily be sent abroad, and someone that has access to it could be like, "Sure, I'll send you some Pringles, but send me back some of that awesome root beer and maybe a box of Golden Grahams."
<bot>: I miss Pringles from Europe, but don't want to pay 10£ a tube for some potato chips. I'm sure some Europeans feel the same way about some snack food from USA. Let's trade.
