If yours has popped off or otherwise been lost, (which seems to happen a lot... heh.) Here's a quick and easy way to replace it! postage update: USPS raised their rates! As of January 27, 2019, postage rates have increased 15-20% across the board. They've also changed to a "zone pricing" structure, which means postage varies based on the destination (and the distance from us to the Buyer). Unfortunately, we were not able to absorb these increases like we have in previous years, and still offer Free Shipping. So, our prices have regrettably needed to go up. We feel that we're still offering the best value possible despite these increases. If you have any questions about these price changes, please do not hesitate to let us know. best value check: On December 2nd, 2014, we found one seller on eBay offering these for $6.00 with free shipping. We're a nickel cheaper and still shipping for free! As always, get the best "out-the-door" price with Kelcema Audio! Need a large order or package deal?
