Made a Whole Foods trip so checked out a different Walmart, and was pleased to find these items. After Ibotta and coupons.com everything was free and a $2.36 MM, incl. tax. There is a rebate for the Aussie. I also stumbled upon the SkinTe so got an FAO.
YMMV, but here are the prices:
Aussie shampoo $1.19
Aussie conditioner $1.93
Garnier treat shampoo $1.73
Garnier hair masks $1.44 (These weren't marked. I asked an employee to check and was delighted at the news.)
L'Oreal $1.20 (The purple one was cheaper, but it didn't match the cdc coupon.)
