New England - Whale watch coupons?

Does anyone know of any fairly consistent source for coupons to go on a whale watch? I'm specifically interested in the ones that leave out of Plymouth Massachusetts, probably next weekend. Regular price is $45 per adult, so some kind of coupon would be appreciated.

Groupon will occasionally have them, but it's not very reliable as to just going and getting one.

AAA gets you two or three dollars off at some of them.

Thanks, I was hoping for something bigger! :-)

Now I'm thinking if we need to pay full retail, this might be a better activity to do in July or August when it's warmer and more pleasant to be out on a boat. I'll be able to keep an eye out for coupons and discounts in the meantime.

My town recreation department has Cape Ann whale watch tickets for $25
