OP, what's on your shelves aren't the best choices of American food. I'm wondering who thought this was worth importing?
Why would Tesco import cartons of Eggnog?
I think the chocolate "shell" and Hershey's cocoa products are a waste. Fox's U-Bet, Nestle Quik or Bosco would be a better choice if you are looking to make chocolate milk or use as ice cream topping.
I think the candy is OK, but as somebody else pointed out, why would you buy American chocolate when you can get better European chocolate.
Boylan soda is ok, but I think better selections could be made. Cheer Wine (cherry soda) would be great. I didn't know there was a Jolly Rancher soda.
I would buy the Pop-Tarts because I like them. And also the grits just because I like grits with lots of butter.
The cereals are ok, but I'd rather have Cap'n Crunch or Chocolate Cheerios.
Two types of Karo syrup are not needed. How much is a person going to use that?
I would buy the Fluff. Jif maybe, although I prefer Skippy. Doesn't seem to be any jelly. You need Smuckers Grape for a peanut butter & jelly sandwich.
A1 steak sauce is ok, but I wouldn't buy it in London because I think HP Brown sauce would fit the bill just as well. I'm not sure what that is to the left of the A1, but if it's barbecue sauce, you'd do better with Sweet Baby Ray's.
If the store is going to stock Hamburger Helper then they need to stock Shake N Bake which is a coating for chicken or country fried steak.
What's missing are good potato chips. Where are the Ruffles, the Bugles, the Doritos, the Funyuns, the Pringles?
Also there could be better cookie choices. Oreos, Pepperide Farm or Little Debbie. And crackers: Club crackers, Triscuits or Chicken in a Biskit.
