Well okay, SOME store have Moutain Dew here, but its only really the big supermarkets, and even then its no guarentee... My local Morrisons (3rd biggest supermarket chain in the UK after Tesco and Asda) doesn't sell it for instance.
I agree though, Doctor Pepper is horrible.
Back on topic... Its confusing me too given GW's '3 months before' rule. In my local store they still have everything for sale, including the army box. Only thing GK they have is a couple of metals like Stern and Psycannon PA's.
As also said, the entire range is meant to be being redone, so why would my manager tell me he's been told that everything will still be viable, and they've been told to keep it on the shelves?
