Although the ebay system says USPS first class is 2 to 5 days for delivery this is out dated information..I have been told by a USPS Post master, that first class has been changed to 7 to 10 days and that if my customers want it faster than that they must pay for priority or Express shipping.. We ship as quickly as we can and we apologize for any confusion that arises from the differing information provided by the ebay system and the reality of the situation.. If you fail to receive a package when ebay says you should have Please don't panic! we have been doing this for a long time and have never had a package lost or fail to make it to it's destination. It isn't perfect but I have faith in my postal service and ask you do as well...
