Firefly with 2 Disc 4's
 

So, I finally received my Firefly Series 4-Disc Set as a gift (which I was hinting for)...

Opened it up with great excitement... lo and behold, I came across two disc 4's (missing disc 3)... I do have the case for disc 3 though...

So... since this was a gift and the receipt is probably long gone... how do I go about getting the third disc so that I can watch this in it's entirety?

just take it back to any store after xmas (the one it came from if possible) This happens from time to time and they will swap it no problem.

Even without a receipt?

They won't give you any money back but they should swap it out for another set no problem.

Stores like Costco and Walmart are actually very good about returns with no receipt (for store credit that is)... but Best Buy and Target get sticky about it sometimes...

On my planet most people keep receipts for gifts. Have you asked?

Or else FOX Home Entertainment does have a disk replacement system set up.
