When I buy something online there's always a pre-checked checkbox as you check out asking if you want to receive emails/offers. I like to support legit businesses so I don't uncheck the box, send me your newsletter or deals, can't hurt me and maybe one day there will be some deal or product I want.
Rather than playing nice and respecting their customers 90% of these businesses go full asshole and spam the shit out of me daily.
No more Mr. Nice Guy.
