URGENT NOTICE: Comics for your Wii problem

Hello,
On Saturday at the UK Web & Mini Comix Thing 2008, we were selling "Comics for your Wii" SD cards containing 2 of our print comics formatted as JPEGs to optimally display on the Wii's photo channel..however I screwed up and didn't test all of the SD cards, it's possible that some of them won't display on the Wii at all due to a formatting bug when they were written, of course this won't do!
I'm a man of my word so if this is the case and you have faulty goods, then please e-mail me at wes (at) gfbowl.com telling me so and give me your postal address and I'll not only e-mail a working card out to you (call the current one a free gift you can re-format and use to save your save files on, your digital photos or virtual console games etc.) but I'll also send you a copy of our brand new printed comic book "The Hitchhiker's Guide to the Shopping Centre" for free.

I'm really sorry about this, and hope the above will make amends. :)
