@sunny: Aww, too bad about the marshmallows, but that's okay! It took me a while to like marshmallows anything but toasted, but I got used to the texture I guess. I really prefer the toasted taste though. Hope you like the Cracker Jacks!
Awww, that sucks that you probably can't get the pizza rolls. D; Maybe one day if you're ever closer to London?
Hmm, for savory, I might suggest Cheez Itz, Club Crackers, Lays Sour Cream & Onion or Barbecue, and Pringles of the same aforementioned flavors. In general when it comes to chips, those two are my favorite flavors lol. I also love Funyuns, but I see you don't quite care for onion taste?
For sweet, Oreos are always good (they have different flavors), and Chips Ahoy! chocolate chip cookies (they have different varieties as well). You can never go wrong with some candy bars, and some of my favorites in no particular order are Twix, Kit-Kat, Butterfinger, York Peppermint Patties, and Hershey's Cookies n' Creme. I'm so-so with Hershey's milk chocolate because of its unique taste, which some will say tastes strangely like vomit. Come to find out that one of its ingredients is actually found in vomit, which isn't to say that they produce it with that bi-product...it just happens to be there? Idk, but I totally wouldn't blame you if I just turned you off from Hershey's. xD
