[GrizHFMinimill] Does Grizzly ever have discount coupons?

I know that Harbor Freight regularly has discount coupons, and Enco frequently has "free shipping" offers, but I was wondering if Grizzly ever has discount coupons that can be applied to the purchase of their mills or lathes. (I did a search through this group's message history, but didn't find anything.)

The reason I ask is that Grizzly's on-line shopping cart has a field for entering a coupon code.
