I had to unravel the Christmas tree lights and fix the blown bulbs last weekend as the tree finally went up.
I needed five new bulbs but I couldn't find the spares that came with the set I'd purchased last Christmas.
So off I go to the local hardware (Bunnings - UK equivalent would be Homebase or B&Q) and I find that a pack of 5 bulbs was gonna set me back just over 6 bucks.
But, for just over 7 bucks, I got another whole set complete with transformer and 150 lights.
