Is it OK to talk sourcing and not just ideas? I don't want to dork up your thread....Send a PM to Sean and see if he will weigh in. The guy is a genius at saving $$ by finding "RC" stuff in other marketplaces before they recieve the 500% "RC" markup and packaging and that adds up to HUGE savings on the small items, just like your bike tire valve thing.
