That's the only way I can do it, one at a time.  Plus I heard from the owner of iheart papers that the prices are going up AGAIN.  They already went up this year. 

I got a bunch when they were on sale at Hobby Lobby for 30% off but a few months ago their ads started saying 'excluding Copics' - PHOOEY!  Now I will have to save up until I place an order that qualifies for free shipping somewhere they are sold online, LOL.
