Buyer pays $6.00 domestic shipping. I do combine shipping so please contact me if you are planning on multiple purchases.
If you have any questions you can contact Bikes & Bits through the eBay ask a question link. Check back as I am slowly cleaning out a 50 year collection of new and used British motorcycle spares.
