I can see no plausible reason for this practice
other than padding ones numbers.
If you can discuss a trade for 4-10 cards, you and
your partner can spend a little extra time to negotiate
4-10 more. There is no reasonable excuse for splitting
up such a transaction into two agreements. A 24-48 time
period doesn't excuse this practice. If it is going to be shipped
in one package it will be written up as one trade/sale.
The CZT has quite enough on its plate without this
Don't attempt to pad your numbers, win a trader of the
month or just simply clutter up the trade agreements
with these transparent end-arounds.
