Considering they don't have a store front (iirc), they would then be limited to selling crates online. There are already lots of dealers selling the crates, meaning they would have to probably bring in a large quantity of them to be able to compete with everyone else's price.
Along with having to compete with the other dealers that have a store front, thus no shipping charge if you go for the drive.
Something like shotgun shells on the other hand might be a better idea, seeing how many much interest there is in their shotguns along with how they sell out of them pretty fast.
My 2 cents anyway.
