Are you able to replicate the error by clicking on the same thing? If so, what is it you are clicking on that is generating the error?

I clicked the link and the page didn't appear to error for me. The trace includes some info relating to coupons - do you have any coupons live? Is it possible to set up a reusable test coupon with minimal value to test with?

It is odd, when it errors, every page load seems to throw it until I recycle the application pool (to be honest I have never left it long enough to see if it cures itself). We have never used coupons at all, but will try and see if I can reproduce. I wonder if a db field type is incorrect?

Just checked and we did have an old live 'test' coupon that has expired in 2010. Have deleted that. Will see if it happens again...
