My access to Bluepoint's web site (they are one of the vendors that I buy IT stuff from) was stopped, according to Bluepoint, because they didn't have an email address to send their "special offers" to.
So I gave them an email address. Bluepointspam@drsolly.com
And now I can check their pricing.
And their "special offers" emails go into a black hole.
Still, I guess they're happy.
