Black Friday ****

What dishonest business practice dislplayed by what I thought to have been "good" company. I'd placed an Item, A Bluetti AC200max portable power station in my cart, hoping it would be discounted on Blackfriday. To my surprise the items price had gone up by close to R5000 rand instead of going down or even staying the same price prior to their Black Friday ****. Please don't fall victim to their **** sale, how dishonest and disgusting to say the least.
