I picked up a massive box of nerds in my local poundland the other day (along with everlasting gobstoppers). Very ****ing happy to see that, especially as they are really expensive elsewhere
Also, Tesco stocks cheetos (look in the foreign import section) -

I know that Iceland stock those weird hula hoop oven chip thingies, in barbeque beef and original flavors.
I really miss wotsit waffles, turkey twizzlers, those creme egg cornettos, citrus polos, and the nice n' spicy pot noodle.
Also, this is really pernickty, but Tesco have just started to separate the cucumber from the tuna filling in their T+C sandwiches (as slices instead of chunks) Still tastes ****ing delicious, but also kind of ruins it.
Oh, and the old recipe of Tesco Salt and Vinegar chipsticks - I was obsessed with the bloody things before they changed them.
