At the Des Moines Bicycle Collective, we're reviewing our volunteer and member guidelines for special orders of parts and bike tools.
Currently, we offer cost plus 30% on orders, which we believe matches what most cyclists could find on Internet sites. Typically, it's replacement bottom brackets, upgrades to fenders, handlebars or derailleurs. We get some Park tools ordered after completing maintenance classes.
Our members ($40 annual membership) can quality for up to cost plus 10%. There is no threshold of volunteer hours for this discount, which is probably worth a second look.
I see that at Community Cycles in Boulder, volunteers need to book 100 hours before earning an increased wholesale benefit (no hint of percent not noted on website).
