Classic Industries sells the M&H harnesses as well. I have noticed a lot of places other than Year One selling them lately, but Year One is quite a bit cheaper, even before discounts. For example, I am needing a dash harness for my bird. From Year One it is $473.99 and from Classic it's $510.99. Since I am not in any hurry, I am waiting for the 30% off to order from Y.O.
Something else that can be done with Year One right now is they are selling gift certificates worth 10% over what you pay, so for $500 you get a gift certificate worth $550
