Dopplr Stickers Availability?

Hey Dopplr Team,

I've been trying to get a hold of some Dopplr stickers, like the one here. I can't go to many conferences so I never get the stickers handed out there and I was wondering if there was any way I could get my hands on one or two...I think they're really well designed and I like them alot! Thanks for the help if you can give it guys...

Sincerely,

Jonathan
