How about some cheap photo paper?
Add this 2-pack of 4″ x 6″ glossy photo paper to your cart. It’s $3.99 with free shipping. Then use coupon code photopaper for another $2 off.
Voila! 40 sheets of photo paper for $1.99 shipped. That’s hard to beat. Heck… at that price, I might even stop cursing under my breath when the occasional sheet gets mangled in my printer feeder.
