Gala is one of my absolute favourite bingo sites and they have an incredible welcome offer at the moment. All you need to do is deposit a tenner and they'll give you a whopping £40 bonus to play with.
The most I've won with a free bonus is £162 and I bought myself a TV with the winnings. What a great day that was!
