A call out to the CBF'ers would work.
How many members have a trove of extra, spare, wet weather, net, just knocking in, couldn't resist in the sale, I'm sure a teammate would like this, haven't tried that make/profile/grade before or I just like willow bats hidden away from their partners bats they could let go for a price that suits both?
There is an argument that this is not a buying/selling forum and you're not buying directly from a sponsor or directly from the retailer. But in my opinion it's all part of the circle of bat ownership and creates a void that will be filled sooner or later.
