@brettb_draws - I'm not very active here, but I got an e-mail notification for this post, so I'll have a stab at it.
From my experience promoting stickers is tricky business. You've got to have a game-plan, something the stickers fit into.
Most of the time, stickers are an operational cost, part of a promotion.
You need to think outside the box (my gears are spinning right now).
Even a clever sticker idea is surrounded by other clever sticker ideas.
How to stand out?
Who to promote to?
OK, not a helpful answer, but I would love to sell some stickers, myself!
I gotta' think outside the box after a long day of work!
Good luck to you!
