On super saver special at $16, however, for some reason, if I add 3 to my basket it goes to $33 from $32. Plus you can get the 25% cashrewards for $8.25/bottle.
Unfortunately 6 bottles is $81 rather than $66 and the 6 bottle 10% discount doesn't discount further (for rewards card).
Make sure you're logged in.
Don't use gift cards. Don't use the app. Better to buy 3 at a time but if you add something else you might get $10 off or qualify for bonus points - check your rewards offers.
