I've recently taken to purchasing a bottle of non-specific brand Cola to drink with my lunch, generally, making my selection from the full sugar editions of the two leading brands.
In doing this, I have noticed that the Tesco Express store which I frequent seems to vary the prices of these two beverages on an incredibly regular basis. This is something I have been pondering for a while, and today I decided to start Cola Watch.
Cola Watch (TM) is going to be a regular study of how the prices of these two colas vary from day to day. To begin, here is photographic evidence of today's prices, along with a plot of the prices against time. I'll try to make updates as often as possible.
