IMO the pay then refund method is going to turn some people away. Especially considering you didnt factor in shipping yet, Then theres the paypal fee. Money is going to be lost between transfers back and forth. Why dont you set up a signup/Poll for people 100% sure so we can get to the $9.99 platform quickly. and pick yourself up a few extra and sell them for $12+ Shipping after the "Pre-Sale" Just a suggestion
