Did a split purchase with valcaus for 2000 keys. The first trade was 150 pure with 50 keys of items as a down payment to put a hold on the item, and the second trade was 1800 keys pure to finish the purchase. Included in the proof is a statement from valcaus on the down payment. The first BP comparison is the downpayment, the second is the 1800 key payment.
