canada has boxing day, when is the shopping holiday where you are.
Couldn't tell you. We have black friday and some other mostly American in name-only 'traditions' the people who run the shopping businesses, I assume, brought to DK, but like I wrote, in name only, because you don't save anything. At best it's maybe 5-ish percent(don't quote me on that because I only check for the things that interest me or I need.), at worst you get outright conned.
It's gotten progressively worse over the years with them also trying to see if you've even checked the price history, so they basically JUST slap 'sale' on it, and try to sell it at basically the same price.
I can't for the life of me take it seriously, so I steer clear of all of that nonsense, if I must shop I do it online, and I find a place with a reasonable price and pay it.
