We have some friends who moved to the U.S over a year ago and they often send us Jolly Ranchers etc... which you generally cant find here unless you order online. We are trying to think of british things to send back which they cannot get there. To remind them of home. Any ideas?
If you look through the products offered by this online store you will get some ideas for the types of things that Brits abroad are missing:
