My preference for magazine subscriptions is always free, but cheap is pretty good too. Amazon is offering various magazines at a $5 discount when you use the code SHAREME at checkout.
All of these and more are available for $5 or less with code: Family Fun, Parenting, Parents, Motor Trend, Motorcyclist, House, and Four Wheeler. There are hundreds more in the discount list, but these are the cheapest. Take a look at all of the options here.
This code doesn’t expire until 12/31, so you have a while to think about it.
