Suprisingly enough, the buttons sold more than the stickers at the event. I would have thought the stickers would be the hot item.
I ordered 175 of each and I ended up with 25 buttons and 70 stickers left over. Anyone wishing to get stickers or buttons, PM me and I'll see what I can do. I'm going to say $1.50 per button / sticker (in USA) to cover the part and shipping which is a great deal!! (as you know, postage has gone up)
