Both holiday promotions are tied to a specific date, but this doesn’t mean the sales only happen then. In fact, Black Friday shoppers can find deals, promotions, offers and coupons before, during and after both sales days. November is therefore an important month for all sellers, not only sellers and vendors who want to boost their Amazon effect. ​​ During BFCM - Black Friday and Cyber Monday days (plus preceding and following weeks), customers’ likelihood to buy increases significantly. eCommerce retailers report up to 240% to 380% increase in revenue on Black Friday and Cyber Monday, respectively. In 2020, Cyber Monday sales increased by 15% compared to 2019, reaching a new milestone of over $10 Billion in online sales for a single day.
