Hi guys! About two weeks ago I shipped a package to Texas with delivery confirmation. The buyer says that she hasn't received the package, and I have lost the delivery confirmation slip (my own darn fault!). I've checked USPS's website and apparently without the tracking number I'm out of luck. Should I just have her take this up with Paypal? I am reluctant to refund her money because the item was relatively expensive and while she was given the option of insuring it, she didn't. I charged her only for the flat rate shipping box. What would you do? Thanks, ladies! I appreciate it.
