Buy 50, get 3 FREE!

From an email we received at work:

I was hoping to speak to someone regarding a change by [redacted] to Credit Card payment for our Staffing Services. Our preferred method of payment is ACH. There would be a 6% increase in services rendered in order to process via Credit Card.

WIDTS: So you’re going to give me 6% MORE employees when I pay you with a credit card? So if I hire 50, I get 3 free?
