MY Hydro Flask customized bottles 34% off and up to 47% off with coupon code! YMMV

I went to see when my Black Friday order of hydro flasks was arriving thinking I got such a good BF deal at 25% off!
But I was playing around with the customized "My Hydro Flask" website https://myhydro.hydroflask.com with my son and he designed one he liked. They automatically are offering 25% off but wiki buy had 10 codes so I thought why not? One time it gave me R10D-525Y which is listed as 25% off but it took off closer to 39% off the 40oz bottle I ordered! Yay!
Did some more testing and this is the weird part… On the largest size bottle, the code takes off 35%?? On the smallest bottle, the discount is 47%. When I try the same code on the regular Hydro Flask website it only took $10 off the order. Hence the YMMV but hop on and order a set for the whole family while it’s working!
On https://myhydro.hydroflask.com as of 9am pst here’s the sizes and discounts in the cart:
