Makes you wonder why it took so long for somebody to make one of these.
Every time I go to Lee Valley in London, I feel like a junky in an evidence room.
When the bill came out higher than expected, I mentioned that I had come to a lower figure when I was making up my shopping list on their website catalogue... the cashier's comment, without missing a beat was: "You may have accidentally been looking at the US pricing, sir..."
JUST the excuse I needed.......
