There’s a slew of coupons you can print off the internet. But if you ever sign up for them, you might not want to use your primary email address. I made the mistake of doing that and started receiving 50-100 spams a day. When I tried to remove myself from a sender, more showed up from other advertisers, etc.. It was like that movie “the blob”. That was in the old days before I knew removing yourself only makes it worse.
If I sign up for free stuff again, I’m going to create a separate free yahoo or hotmail email account for just that purpose.
