I hope amazon doesn't just send another message if my transaction didn't complete in 5 seconds. I think like all pieces of wisdom, sometimes it's OK to let it fail, and sometimes its OK to handle the errors. If anyone ever tells me to always do X or never do X, it's typically not sound advice. The one thing we can always count on is generic advice failing sometimes :) (And even in this article, you shouldn't always try to handle known errors and never try to handle unknown errors, there will be exceptions)
