I've already bought and made one when they were half price. Usually I bake from scratch, but as Christmas cake is something I make because others like it, not me, I was happy to cut a few corners. The kids helped make it. It baked OK, but the temp and time didn't seem right and it was a little over done. Nothing that couldn't be fixed with a bit of a trim though.
Today I was doing my Tesco shop and they were reduced to £2. I bought one and have baked my Dad a cake now as well. I reduced the temp to 100 and the time to 3 and a half hours (instead of 4 to 4 and a half) and it looks perfect.
Bargain extra gift for my Dad.
