Sure but I imagine they are not alone. Eg. IKEA does the same thing as I recall: "refund" as store credits.

Someone should create a website for class action lawsuits.

There are already quite a few sites which list existing class action suits and how to sign up for them. I'll check them sometimes and see something about false advertising for a granola bar I bought six months ago so I put in my info and then get a check for $0.87 in the mail a year later and have absolutely no idea why.
