Sure! I was actually in the midst of an exchange but the person hasn't answered in a week, so maybe this will start the ball rolling. I am hoping to get this book and if you'd like to throw in there, Tyrell's Sunday Best Roast Chicken crisps, Pret Mature Cheddar and Onion crisps, Toffee-flavored Kit Kats, Kinder chocolate with cereals or anything you think would be good, I was just in London last month for a 36-hour layover so those were things I tried and liked.
Would you like something specific, flavors you like/dislike, and set a budget?
