There is currently a sale where you can get 6 ezmix preset bundles of your own choice. Price is great, and I have bought this 6-pack.
Just one question which is not clear to me. I was sent 6 authorization codes. Can I save a couple of those for later use, or is there a time limit? Having already bought many preset bundles, there really are only 3-4 I would want buy at the moment. So can I wait and see if you come up with something more interesting to me before I use the last few authorization codes?
