< Just take my money and go away.
I need to be less lazy and sign up for a credit cards that gives you a unique card for each purchase, and the email address system that give you a different burner email for each transaction.
The worst (if there is a worst) is when you click the box that you don't want to be bothered, but yet they continue to harass you. I no longer shop at Khol's because of this; for some reason they think it's their god given right to send you as much spam as possible with no way to actually unsubscribe, except they made the mistake in thinking that I needed them for some reason, so I just blocked them altogether. Not that it really matters; for every 1 person that blocks them for being a pain, there are 1000 other people thinking that the spam they are getting is some great service.
Idea... when a store asks for your email, give them the support email address for that store :)
I give them "webmaster@goatse.ru".
part one complete, signed up for https://burnermail.io/ and installed the extension. Now I just need to find some credit card middle wear that I like.
