Some LLLL sell for low xxxx every week, even with 'crappy' letters, but it's hit and miss to try and pick what will sell. I'd be selective about what you buy and at least have some reason for picking the letters. At least you just paid over reg fee for each ($12). If you are buying to invest, then you need to earn close to $600/yr in sales or ppc just to cover renewal fees - that will tell if it's a good buy or not.
