My girlfriend has the Sex and the City complete set. She hadn't watched all of the discs and actually listed it on Half and sold it.

Before sending out, she was flipping through the pages and noticed that she had received duplicates of season 6, part 2, disc 2. So, as a result, all of the eps are there, she's just missing the extras on that disc.

What should she do? She's supposed to send it out tomorrow. Should she try contacting the company and get it replaced? Should she tell the person she sold it to to try contacting?

She got the set like 2 years ago, so she can't return it and send out a new one.

I had a similar issue with one disc missing as well. If you call HBO corporate office, they should be able to help you. What I had to do was send in the disc that I wanted to be replaced and they will send the correct disc. This was a few years back that I did this so not sure if their policy has changed since then. Good luck!
