Discount codes uncoded

I finally know how to create a discount code/coupon code/voucher, so that I can offer CADDi specials.

The first is for MSU. I'm told CADDis are perfect for tailgating and that's where my interns are and we're going to do a little MSU awareness campaign. I was hoping to offer a buy-two-get-one-free deal, but the code doesn't work that way. $1 off it is...just use the code MSU.

In retrospect I wish I'd used another code, so I could send it to other schools, but that'll be later. For now we'll track this and see how it goes.
