I would, but it's such a hassle to enter my address and CC info on every manufacturer's site. The last 3 things I bought were shaving cream, toothbrush heads, and a cheap tennis racket.
Do I really want to signup/purchase/unsubscribe-from-spam for a Proraso account, a Philips Sonicare account, and a Wilson account?
Perhaps Google Pay could add a useful layer here.
