Your coupon may be dated different than the two I had but mine were only good till the end of July. Just FYI!
I unfortunately sent mine to someone to use and have never heard from them since. So, I don't know if they got to use their half and then just never sent me their info so I could use mine or they just decided not to use it.
I even attached a note to the coupon so they knew they had to get back with me so I could use my part.
I had my eye on some forks or possibly a wider bucket!
