I’m not sure why I’m even responding, since it seems like you’ve already made up your mind. But just to clarify... when I started with Bucksbus, I didn’t pay 35K upfront. I began with their standard rate of 0.3% on transaction volume. I only decided to purchase the transaction package after trying the service, as they told me I could switch whenever I felt ready.
You don't seem sincere about the fact that you need a payment processor; you're acting more like shilling for Bucksbus.
