On our Being Frugal 101 Blog, you frequently see Free Samples listed. If you have followed these links to get these free samples, you will see that 99% of the time, the site asks you to enter your email address. You enter your email address to get the free sample, and then have to delete all other incoming emails from this site or have to cancel your subscription with them.
A quick, easy way to avoid needing to do this is by creating an email address just for your couponing & free samples. By doing this, you keep your email inbox from getting cluttered. You can access your new couponing/free samples email account when you are ready to look through the available coupons & free samples you had sent to that account.
