We do not provide free stickers. Our preference is to treat all customers fairly and consistently. Giving free product to some people, but not others doesn't fit with our values. For the same reason, we also do not provide discounts to our service.
That said, our sample pack is available for A$1 and includes stickers from some of our favorite brands including Twitter, GitHub, Google Chrome and Dribbble.
Alternatively, you may place a small order of custom stickers with your design using our custom samples service.
