I will just say that I purchased three times from this seller in April last year and received all three items promptly (cattle wagons and chnia clay wagons)- and this was one of my feedbacks for him:
"very quick postage, good comms, combined payment, excellent, thank you"
Whilst I don't recall anything specific about this purchase, I clearly had some kind of contact e-mail with him, probably about the payment combination to save postage.
So I contributed to that 100% rating....
