Does anyone know a vendor of Muzzy's lowering links that will ship USPS ?  Muzzy's only ships UPS and their brokerage fees are far too excessive for us frugal Canucks !!
Any help appreciated.        ICBM

If you're not in a hurry, try ebay.  I picked up a set of lowering links for a good price and the seller will work with you on shipping. 

I picked mine from ebay for $35
