One black friday sale from a website stated "Up to 55% black friday sale!"

I've been getting email from them for several months and the same product that's being advertised as up to 55% off was the same product that's been 55% off for the whole year. The next biggest sale to that was 20% which has also been there for the whole month so far. Granted the platform/site is great and have amazing customer service/return policy/etcetc but it's one of those sites that has a "constant sale" on some items. Like that's not a sale.
