A Query, A Plea, A Shot Into The Night

Is it just the Northeast, or are peanut butter Twix unavailable all across this great nation?
I ask, because the caramel variant is a poor relation, an imitation, a candied poseur of the first order whose continued existence in vending machines and on store shelves is unexplainable. Their wrapper is a mockery of proper palates, as it holds out the prospect of its far more delicious sibling with a “Why not try Peanut Butter Twix?” Oh, M&M Mars, thou foul temptress! Why dost thou mock me so?
Also, do y’all get mint M&M’s at any point other than around Christmas? They used to come in a “minty” green bag, right next to the almond ones…
