I feel this is the year Black Friday really has become a thing in the Netherlands, mostly online though. But there was Black Friday discounts at stores as well. Even though it's not as big as in the States and the UK, I suspect it will be within five years. Cyber Monday might become big as well. On Cyber Monday the discounts are usually higher than on Black Friday, yet Cyber Monday wasn't that big. But this will become big as well.
