Shipping cost doesn't mean anything. Total cost for you is the total cost for you. So don't get hung up on what category the cost is associated with.
II Sports used to be a big chain. Like all paintball its super small now. I imagine them just clearing out old inventory as a hobby. Rummaging through stuff for your 4 dollar part to save you shipping doesn't fit the model. They don't have the manpower. More orders will be screwed up.
Nothing personal. They just have a system and don't really care about these old inventory parts flying off the shelves.
