Ok this Indiegogo project is nearing it's end and it's a great deal. They're a few hundred dollars away from their ultimate goal.
http://www.indiegogo.com/aussieblockdice?c=home&a=1166757I made a $15 contribution and for that $15 I will be receiving 3 sets of block dice and if the campaign reaches $7000 there will be matching d6's as well. Throw in free international shipping and it's almost a no brainer. Have a look. Because you can never have too many block dice.
