I've normally thought of it as a retailer thing, but it does look a bit like it's brand-led in some cases.

I'm currently in the market for a few big ticket household items, and the Black Friday hype is everywhere I look. When I try to compare prices for specific models, they are suspiciously identical everywhere, with a few outliers charging the higher RRP.

I would expect a retailer-led approach to have a bit more variation. Just a few quid here or there, where some might have a genuine "clearance" need, others lower general overheads/margins etc.
