HELPFUL HINT! If you plan on buying more than one item from me in a particular session then please wait until you have finished shopping before paying for these items.  This will insure that all the items will be shipped in the same package and all items will have the same tracking number uploaded to the Ebay site for your access. Thanks for you help!!
PLEASE, if you plan on buying more than one item from me then put them in your ebay shopping cart. When you done you can go to the cart and pay for them all at one time. That way you will have one tracking number and the chance of losing packages will be greatly diminished.
Officially Licensed Schwinn Product.
