If you do feel like putting an order of weird British stuff, I'd recommend: Tunnocks Snowballs, Ribena Sparkling Blackcurrant, Jacob's Jaffa Cakes, Chivers UK Lemon Curd, Hula Hoops Variety, Twiglets, Tunnocks Milk Chocolate Caramel Wafers, Custard Creams, Twirl Orange.
All delicious!
Dunno how D & B's made, but American root beer isn't made with the "real" ingredients anymore. They're banned because if you give a megadose to mice, sometimes they get cancer. One of those "maybe actually bad, but maybe not really and just overzealous regulation" things.
I mean, also I'm sure it's cheaper to make fake-flavored root beer, but there'd at least be some craft ones making it the real way. But no, it's banned.
