Just for fun, you can contact Vultr to get free sticker.

On the registration page I found a place to enter the Vultr email account, not sure how the mechanism of reviewing the chance, just register it.
Vultr is a very good, stable, and reliable provider of Cloud SSD VPS services that I trust for CouponTree, Techmine and many other websites. Vultr has Japan & Singapore locations for fast and stable access.
