I've had the same problem off and on. It appears to be intermittent so support has not been able to reproduce the problem but said they'd continue to monitor it.

Thanks Dale.

I should clarify: I realize we can test the checkout by purchasing something, but I really don't want that in my sales records, and I would rather not have to process a refund, as that creates more records too. :)

I hear ya! My sentiments exactly but I don't have an answer to your question...just empathizing. :)
