I had a similar situation with my eBay vendor and here's my take on what's going on. This is a Catch-22 situation for the eBay vendor. eBay tells their vendors the they must ship using the eBay preferred carrier. That is a company called Speed-PAC. The problem is that Speed-PAC will not accept any merchandise that contains an integrated battery. What's the vendor to do? Some simply remove the battery and ship via Speed-PAC leaving the end user to solve the problem for themselves. Other vendors ship a "free gift" using Speed-PAC and include a note of explanation. This satisfies their requirements with eBay, but leaves us wondering what's going on. They then ship the real merchandise, with battery, using a different carrier. It's a clever solution but it's annoying for the end user to be sure. In my case it took a little over two weeks for the "free gift" to arrive and then a little less than two more weeks for the VNA to show up. Yes, the outer cardboard box was crushed but the contents were fine and as expected.
I offer this for whatever you might think it's worth,
