Please list the businesses you'd like to see as sponsors here. I think it carries more weight with them if I can say people have been asking for them.
Since you've talked to them why don't you invite them here? That's better than me doing a cold call.contraststriker said:Thunder Racing and WS6store!
I've chatted with WS6store and apparently they'll beat any price you find, period. Even if it's on ebay! (given it's new and a buy it now price) They're super easy to work with and I've personally ordered stuff from them--prompt shipping. Oh and sometimes they work with Thunder so between the two of them you'll definitely get good prices.
