I have never bought a one-coat paint, but I have found some paints can be used in a single coat anyway. Wickes white emulsion (in the 15-litre pots) is pretty good in my experience.
The addition of the word "digital" to everything that Argos or Dixons want to sell for a few extra quid.
Has anyone every gone back there and said "I plugged these digital headphones into an spdif connector and couldn't hear my music! Give me my money back!"
Just a note about the mobile phone one. I think most manufacturers quote 'up to xx hrs' for the battery life. This is because under certain conditions you'd be lucky to get 25% of that even with a healthy battery.
