I had a sale this afternoon, with the question attached "I want to buy item, what do I do next"
So I sent invoice in which I reduced postage as it was combined items, and sent a message via ASL as to what I had done and advised on how they could pay.
Got a message back twice, "I want to cancel my order"
Half hour later they paid in full.
So I have now sent them another message do they want to cancel or not.
