Title: An Extra Comma Appears When Using A Coupon That Gives Free Shipping

There's an annoying comma when you're using a Free Shipping coupon without a price discount. It looks fine when there is a discount but not so much when it's just free shipping. I made sure that any empty array elements are removed so there's no comma.
