Sign up for Logan's Nut-E Club and you'll get not just a birthday gift, but also a welcome offer and an anniversary gift. You will get a $5/$20 purchase coupon as your welcome gift in your inbox immediately after signing up!
NOTE: These don't work in all locations. The website states they are not valid in CA, NC, SC or Augusta, GA.
Over the summer, I'll be posting more birthday offers, so be sure to refer back to the full list for any that you may have missed.
