In Mexico there is also something similar called "El Buen Fin" but it is trash, there are only months without interest and no discounts

This year actually felt a lot smaller. Last year was the first time it was really a thing, and its wasn't that big, but people made such a huge deal about one fight in ASDA (the OP pic is from last year) that some retailers just aren't taking part and most of the big sales are online.

Boxing Day Sales remain the best.

ewwwww
isn't the UK have boxing week too? it's a whole week of sales and yet some are fighting for some Black Friday deals
glad Canada keeps it classy we have only had Black Friday for a few years, and the deals suck comparing to US Black Friday, so everyone kinda waits till boxing week

South Africa too. Checkers Hyper did it today and it was a mess(people were fighting and some were stealing things from other people's trolleys.

Judging by the pics I saw it was a huge success so it's gonna be a big thing next year coz more retailers will join in
