Certain entrepreneurial individuals are hitting up all the retails stores within their driving distance, buying up their entire stocks of sanitizers, masks, and all sorts of other supplies that are in high demand, which they are then re-selling on-line at Amazon, eBay, and other such venues for mega-markups. To read some of their interviews, they seem to not have a hint of a clue of a concept that this might be frowned upon.
More recently, the on-line platforms have been cracking down, suspending or banning these accounts, leaving these resellers with literally tens of thousands of units to sell and no venue to sell them. Meanwhile, the rest of us can’t get any of this stuff because the shelves are bare.
This is flat out illegal in at least some states, and some district attorneys are starting to take notice.
