Dazzledayz, meekamag, as I re-read my post yesterday, I realised I'd worded the "message" in a way that I itched to reword. Yes, something like, “Would you like to proceed or would you prefer to cancel? Please let me know within 2 days; I will assume that you wish to cancel if I do not hear from you within that period.” Or that effect.

Then, as said, buyer requesting cancellation is the reason to select when cancelling.
