I check the prices on the three Wellness foods listed below every day . A few days ago, I noticed that there was a 15% off coupon for your "first" S&S order. I have bought this food monthly for many years, so I put "first" in quotes. Then the next day I noticed the coupon increased to 25%, so I canceled my orders and re-placed them with the higher coupon.
Today, on a whim, I decided to check the price again, and saw that there was a mystery coupon applied, bringing the savings closer to 40%.
I tried a few different Wellness products and saw all of the ones I chose had the same 25% plus an additional mystery savings. I did check my spouse’s account (non-prime) and that account did not have the savings, so either it is YMMV or prime only.
