How to Swindle Soldiers

According to The Washington Post, these three companies: USA Discounters, Freedom Furniture and Electronics, and Military Credit Services, sell goods to service members on credit and then, if they fall behind, go after them in Virginia courts, regardless of where the service members are based. Together the three companies have filed 35,000 lawsuits in a little under a decade.
Anybody deal with these companies? Any others we should know about?
Definitely candidates for a commander's list of off limits establishments!
