I purchased an 18v cordless electric electric drill for £12.99 about $30?, anyway , I was so pleased with its performance for the price, which includes a 5 year guarantee. Inside the box is a card advertising replacement batteries for the sum of £15.99, so I thought I had better have a standby, I was on the point of sending off the card for the extra battery, and I said to myself , this is crazy, I can buy anew drill and battery for £12.99.
The wife was in a good mood, jumped in the car and popped down to Woolworths for me, I now have a spare drill.
What I am trying to say is that the battery manufacturers must be ripping us off if you can buy their product cheaper in this unconventional manner.
