Often companies online state that they have "limited time offers", where you can buy a product for a discount.
However, i'm sometimes suspicious about this, and suspect that they're not limited offers at all.
Are companies allowed to say "20% off! Offer expires in 4 days!", but then when those 4 days are over, simply wait a day or 2 and start the offer again? Or is this prohibited by consumer protection laws?
Edit: the jurisdiction could be either the US or the UK.
