Country Clean Paper located a few miles from x105 on the parkway is a great place for boxes, boards, cake and cupcake containers, syrups as well as baking (not food) and party supplies. Small, very clean store and they are open to the public. Best of all, you can purchase items in any quantity. You can see all their inventory and get add'l info at their website.
(Not sure if this has ever been posted.)
Thanks! I work right off Exit 105 so this would be so convenient for me.
