Thanks for joining us here, I can see you have put a lot of work into your deck, so well done. I usually really appreciate anyone that can customize each and every card in a deck, the #1 thing that stopped me immediately was the $2 shipping to Australia. I do not believe this is possible. But alas this cannot be changed now. I do really like how colorful and unique it is!
I would recommend including more information on your project page, for example; what company will print the deck. What company is shipping the decks...etc. Don is a genius, this should totally be a plastic deck. You do have an advantage of appealing to a niche market, so if I were you I would be contacting alcoholics everywhere. I don't know where they are, but you seem to know all about drinking so you can probably track them down...
The last recommendation from me is a disclaimer, along the lines of; If you die of alcohol poisoning you are not allowed to sue us.
Good Luck with your project!
