Hiyo~ I'm taking commissions, and am trying out something new to make this process a whole lot easier. No more dealing with the restrictions and lack of buyer and seller protection of PayPal.
I'm using Commiss.io to organize my queue, give all information about my types of commissions, show clear examples, and allow you to purchase a particular type of commission straight from the site. No need for an account or anything. And they use Stripe for payment processing, so they have all the flexibility and security that affords.
So! Buy a piece! Try it out! Please? :D
