I was just thinking about the method of purchasing the pre-alpha can be quite confusing to some. I say this because Backerkit only allows the use of credit cards to purchase the Pre-Alpha tier. I, myself, do not use credit cards but instead use debit. So, I was just thinking, why not use the Humble Widget to sell the pre-alpha on your website? It would allow users to purchase the pre-alpha using paypal, debit or credit. Just a thought, anyway.
