Tim,

To supplement Oscar's remarks the MRA will have all your sticker needs taken care of.
We have a contingency tower available each race weekend with forms and stickers from our providers.
We will have a bin for each supporter of contingency and we will work with them to stock them up for you guys.
No need to call all of them directly, but feel free to talk to them as needed.

Hope this helps.

Regards,
Aaron Fisk
