This might be something to pick up for the kids to keep them reading this summer. National Geographic magazine for kids is available for $15 per year.
That includes 10 issues- so $1.50 each. I brought one of these home from a trip and my kids loved this magazine.
If you have little ones aged 3-6, they also have National Geographic Little Kids priced at $15. This one comes with 6 issues per year. You can order National Geographic Little Kids here.
