I tried flying out of JFK in New York on Thanksgiving Day once. What a nightmare. It seemed as though all of the airport workers were on holiday and nothing was happening. Our aircraft was parked at a remote location on the airfield and it took ages to find a movements team to drag it to the departure gate. We were delayed for about 5 hours.
Also, I wonder how many peole that are declaring they got a bargain and saved loads of money, were actually thinking of buying what they ended up with. I could 'save' over £50 buying the inflatable bed below from Amazon, but as I don't actually want want, I would have actually wasted £70!
I found it interesting as I was looking to buy an electric razor for my nephew for Xmas. Looked at it on Amazon and it was £44.00. Went to buy it 2 days later and it was £56.00, a few days later it was £77.00 then the Black Friday deals and it was £44 again with a big banner of being 40% off. The deals are not always exactly real/
Caveat emptor applies constantly imo!
Examples like GB72's above have always existed, and, imo, will always exist. If sufficient examples are identified, the retailer's reputation could well suffer, so that's a gamble on their part - but it most likely wouldn't stop me from buying from them if they were still cheaper than elsewhere and I wanted the product!
