Monopoly Classic for £11.82 with free shipping is a good offer (Amazon) for anybody who could do with upgrading their set for xmas!
Amazon has long forced all of their sellers into a race to the bottom anyway, none of them have got any margins left to play with. That's another perspective on the lack of decent offers. I'd be making a loss if I reduced my prices by 30%....
... I've got 2000 product listings on various marketplaces including Amazon, haven't reduced a single one. My sales increase on this day irrespective of whether I discount, working double hard for no profit doesn't appeal to me.
Almost all products offered on Amazon at a discount today with a 'black friday' tag will be being sold by Amazon themselves, not third parties.
