Edit: if you prefer $25 e-wish gift card instead then use DRH
I spent $30 last month of pet products and got a free month insurance. The code looks generic - JULY1M. It seems like the everyday rewards number is non-compulsory. It's only 1 month but hey someone might make us of it more than me. You can always make claims and cancel thereafter (not that I'm supporting such action). They also need approval so you can always bluff and say you forgot your rewards number but enter it in after the 1 month.
Gives a new meaning to the 'pet food' fridge! You know… for the ones who don't make it.
