Black Friday. Biggest con to ever hit the UK. Firms selling off old stock/unshiftable stock that was probably cheaper 3 months ago
Just be a savvy shopper all year round. Use cashback websites like topcashback. The referral fees paid by companies to get you to shop goes back to you.
Most high Street retailers are on there, get your referral percentage paid back to you and earn a few quid back.
For example, buy anything on eBay in next 24 hours 6% cashback, treat the wife 11% cashback at monsoon, 10% cashback at Currys.
They charge £5 a year, it comes out of your first years earnings so you don't pay anything up front. Not a massive online shopper but earnt over 3.5k back in 11 years just buying 2xcar insurance, 1x home insurance, gas/electric and sky/bt.
I don't work for any of these companies but happy to tell you how to save/earn a few bob dealing with companies you've probably dealt with for years.
