Maybe the food section is better?
You'll find tortillas, soft ones both flour and corn, and premade taco shells...I never did find plain salted Doritos, though. (Original Ranch, yes.) Plain Tostitos, I found. They sell lots of salsa, not sure about Pace. What they don't have in the UK is the amazing selection of crackers we have in NA. No Triscuits, Stoned wheat thins, Wheat thins, Cheezits. Carr's, they have. Polish delis usually have some kind of dill pickles, but otherwise difficult to find. I'd put a few packets of onion soup mix (if you like making the dip) and Ranch dressing mix in the shipment.
Someone else should know about the creamer and Rice-a-Roni.
