I will have one block card please but not a clue on what you mean about specifying the block because they are pre allocated when you mine?

So how would I select the txid?
Message me directly if needs be! Ask john Kim to put you in contact with Richard butler (litecoin Rich) from uk please if needed
You need to send payment for the block and shipping. Then post the transaction IDs of your payments. If you have trouble finding your payment transaction ID, tell us what wallet you are using and we can help.
