Got this email from Martin Print. You can get 50 free stickers from their website, which was posted last year. BizzBuzz also did a 100 free stickers offer with them but has expired.
Now all you need to do is to Facebook-Like their page and you'll be able to order 100 free stickers from them, with your own custom design and free shipping! Those stickers are 45mm x 45mm so pretty small.
First time I ordered these they didn't turn up.. Second time they did, cant complain for free tho! Was considering getting more stickers from them the first time and decided not to as they didn't come, but now I will.
FYI they come form Perth so they take a little while :/
Might want to add Scotty that they are for business only.
