Theres at least one that offers something like 3%, and IIRC gives you £100 for switching banks to them. And no matter what, I can't get much worse than these bastards, they are liars and penny-pinching cunts. Christ, I've even been lied to (three, maybe four times) about them sending out a new checkbook. I don't use checks very often at all, but I needed (and still do) a new checkbook for the odd foreign place that doesn't have paypal or visa debit facilities, such as one ethnobotanicals store specializing in african Ubulawu supplies and since I can't login to one of my payment-processor go-throughs I can't order from them until I get a new checkbook.
And the reason for needing a new one is..unusual to say the least. Something melted through a dresser, through the top and carried on burning through the checkbook until not one was usable and they had been turned to dust. I don't know what or when exactly but whatever it was goes through several inches of wood and keeps on going, like the acidic blood of the creatures in the 'alien' series of movies/books and the moment the checkbook was picked up it partially disintegrated, and the rest was all powdery and puffed-up.
Every time its been 'we'll send you a new one right away' and never have I got one, I'm still without one.
