My brother, ever the cheapskate, decided to buy a used couch. I guess you know where this is going...

The $500 or so he saved didn't come close to the cost of full apartment treatments, the headaches, and being basically outcast by the family for a month.

Protip: Unless you're really hard up, don't buy a used couch or mattress. And if you have to, figure out a way to deep cleanse it first.
