I've had great success using Teachers Pay Teachers since I started my "store" 3 weeks ago. Thank you all for your support!! I really hope you enjoy my products. I discovered it has been well worth my time to share the materials I made for my class.
I found a similar program called Teachers Notebook. There are no commissions, but there is a one-time setup fee and you get charged a PayPal transaction fee. From what I can tell, the overall profits for low cost products should be about the same as TPT with a Premium Membership. I plan to post my materials in both places, so feel free to take your pick. I'll update you soon to let you know how it goes, and which website is more successful. In the mean time, check out my Teachers Notebook Shop!
