One option might be to move out your handling time to give you an additional buffer. I have mine set at 3 days, but did have it as long as 10 days last year. I think I might adjust it again to err on the side of caution, especially in light of current delays.

I agree that Ebay is all talk as often the things they say are supposed to happen automatically never do and sellers always have to chase and chase until it gets rectified.
