It really is convenient. I feel fortunate. I go by there a couple times a month so I just keep my wish list up to date and pick up whatever is on the list (get it ordered a couple days in advance).
So I added four more Strawberry Biscuit mixes. Your mix is 66/34 (non-strawberry/strawberry). I added a 40/60, and three more spread evenly in-between. The ratios between the two strawberries are the same as your recipe as is the five non-strawberry flavors. The only ratio I am changing is the non-strawberry base vs the strawberry. And I keep the 10.25% flavor strength throughout as well. I should have this one bracketed. Now I wait.
