So is there any craft supply that you feel lost without? I found that mine is ATG tape refills. I ran out and was waiting for my Joanns to restock...they never did. Both of my closest stores have not had any refills for the past month! They are still stocking the gun so the fact that they are not stocking refills for it is pretty stupid. I gave in and ordered 12 on ebay so I should be set for awhile when it gets here.
Once you use an ATG gun it's pretty hard to go back to regular tape runners. The regular ones run out SO much faster and the tape isn't as good.
