Early adopters - that's what they're called, and the technology industry loves them. They fuel the hype around a new product. There's no harm in it - lots of people love having that new iPhone on the day it's launched. Apple has perfected the technique of producing objects of desire, especially when it comes to phones.
So it is you that is clearing the shelves at Aldi. Every time I go the offers have gone.
Had occasion to wait outside a Lidl store one day waiting for them to open, (Not for their offers I might add). There was a group of people with a large number of children who rushed into the store the moment the doors opened and stripped the centre aisle shelves of the offers. The children gathered up multiple items and waited for the adults to catch up with them. I can only assume that it was an organised 'raid' and that the items were going to be resold at Boot Fairs or the like.
"Let the early adopters buy them and find out what the problems are..."
That's what most people do - they're the cautious adopters. A big interest of mine is photography, and earlier this year I attended the Photography show at the NEC. I saw dozens of people who couldn't wait to get their cards out to buy new cameras costing £1000 or more.
