Saw this grinder in the watford tesco store today, marked at £11.74, online at £14.99http://direct.tesco.com/q/R.207-0283.aspx
it swiped at £7.00, so I bought 1, had about 5 left on the shelves.
Quite probably a mis-price so may not be national. This same product had been on HUKD before at £3.74 which is why I've had my eye on it. I still think £7 is a cheap, so may be worth a try at your local if you're in the market for a grinder.
ps: till roll, just says "Angle Griner £7.00" so please don't ask me to scan and post it...
Hope this helps someone out.
