Welcome Brian. Thank you for taking the time to post so much information for us. I have always included a packing slip out of fear that the label gets ripped off but I will now start actually taping that slip to the holder, good advice.
I hope you are able to find some cards you like here - and you might even have a new outlet for your sales in our Buy Sell Trade section (no fees!!). I am happy to hear that this situation had a happy ending -- here's to a happy ending for everyone!
