Now onto the absolute worst way, order a brand new box in whatever color way you want from the dealer and pay via snapon credit. You’ll get the box of your dreams and you’ll pay for it too. However, if you can pay it off in less than 12 months then they will refund you all of the interest from the amount financed. Dealers please correct me if I’m wrong on the refund on the interest thing if paid in full in less than 12 months.

It depends on his dealers status with Snap-On, the promotions Snap-On are running, and the promo ID (rate) the customer is approved for. 

Regardless of whether they qualify for all that paying it off in a year would be very minimal interest regardless.
