I've tried it from 3 different computers. From the wish list and without the wish list. Signed in before starting order only to be required to sign in again as soon as I hit Check Out which 0's out the cart. Not signing in before starting order only to have the cart 0 out when I do sign in.
I just figure they don't want my 100+ buck for flavoring. I'm not going to worry about trying again until I have plenty of time between activities so it will be an exercise to combat boredom rather than the exercise in frustration it has been.
Will check into this and see what's going
