I intended to put a slip with the promo cards to explain how to use them, but in my hurry to get them out, I totally forgot to do so. Here is how they work:
Players may replace up to 4 wild cards in the deck with the promo cards. If one (or more) are dealt, the player may choose to play the "Charity" card instead of influencing a sister. The player still only plays 5 cards in a round out of the 6 he/she is dealt. When playing a "Charity" card, instead of influencing a sister, place the card on the table, and take either 2 gold or 2 fruit from the supply.
Hope that helps, let me know if you have any questions!
Shipping update: As of tomorrow morning, all $45 reward levels will have both the game and the promo cards (if you didn't get them with the game) shipped. I am working closely with a t-shirt company to get the shirts done, and levels including a t-shirt will ship as soon as I have the shirts. I apologize for the delay with the shirts, but I want to make sure they are done correctly and look good. Anyone above the $45 level that doesn't include a t-shirt will have their item(s) shipped early next week. I sincerely appreciate you patience while I get this problem addressed.
