Why can't I jump on "World Grocery store" and buy any food item I want? Let's say I went on a trip to the United States and really liked that one chocolate, but I live in the Czech Republic. Even within Europe you can't just buy whatever you want and have it shipped to you online. Let's say there are some goods that I want from Spain. I need to ask my friend to buy it and then ship it for me.

Why doesn't a website like this exists? Am I missing something?

Edit: When making this post I didn’t have meat and dairy products in mind. Just stuff like chips, chocolates, etc…

Edit 2: I’ve seen lots of comments say Amazon, I already looked into it and 90% of food products do not ship internationally. Thank you to everyone who commented the reasons why this idea isn’t done on a wider scale!
