A Question of Integrity- Where are Morals and Ethics in Today's Society?

Maybe you can tell from the title of my post that I am pretty aggravated this evening. I'll explain why. I purchased a new DVD player to replace the one that broke (as I mentioned in a previous post) this afternoon. There were 5 available at the store, and 4 of the 5 boxes looked pretty beaten up, so I examined the one that was in the best shape. It looked as though the packaging had been tampered with (it had obviously been re-taped shut). So, I took it to the Electronics desk and asked if it could be opened to verify that all of the contents were there. Sure enough, there was a DVD player packed in thin styrofoam (could see it's shape, but not exactly what it looked like), there was a remote in plastic tucked neatly on its side in a niche in the box, new batteries in shrink-wrapped plastic, and the Philips warranty card sitting on top. It looked as though nothing had been tampered with and everything was there. So, the Electronics guy re-taped the box and I bought it. I opened the box this evening to set it up and put in a VeggieTales DVD for Ethan, when to my surprise, I found that inside the styrofoam was an old, scratched up (obviously used) RCA (not Philips) DVD player with an RCA remote, and several cords were missing along with the manual. Someone had taken great care to remove the new DVD player and repackage their old one (including their remote) in the exact same manner as the new one had been packaged. I can't imagine the gall of someone doing that and then returning it. I was immediately concerned that my integrity would be questioned when I went back to the store and explained what I found because there was no way for me to prove that I wasn't the one who did it!! I was upset that I had been put in the position where I would be scrutinized because someone was so dishonest as to steal a new DVD player from a store and return their old one. Thankfully their customer service, though a bit skeptical at first, said that this often happens. They call it "bait and switch" where an item is purchased, something is put in its place, and then it is returned. They said that recently a $300 trampoline was purchased, someone carefully repackaged the box (even re-doing some strong plastic ties) and returned it, when the box actually contained scrap pieces of wood instead of the trampoline. Thankfully I was able to exchange it for a new DVD player (in one of the beat up boxes), and customer service opened the new one to verify its contents before I left the store. Before I make any future electronics purchases, I'm going to have personnel verify the complete contents of the package before leaving the store. How sad that someone thought that doing this was ok... Ugh.
