The creators of the blanket have reached a settlement to pay $7.2 million for misleading advertising.
Here's part of a statement from the Federal Trade Commission, explaining why:
In March 2015, the FTC alleged that since at least 1999, Allstar used direct marketing TV commercials to sell its products, many of which are familiar to consumers. While the products varied, Allstar’s pitch often was the same—a “buy-one-get-one-free” offer that did not disclose all the costs. Because the ordering process was confusing, some customers also were charged for more products than they wanted.
