That's what I do, auntygeek, though I don't always use the odds matcher, as I've primarily stuck to PL, Championship and FA cup so it's easy to just tile my bookies window and exchange window and look side by side. As I branch out into the European leagues I'll probably use the odds matcher more.
I haven't done the same as you re the offers, I've done most of the beginners ones then started mugging and reloading as there were some good reloads coming up in the weeks before Christmas, so I went with some of them. Going back and doing some of the advanced offers now.
Jon you do well on the slots but you seem to spend a lot of time on them! It seems to be worth it if you can do it though.
