The Gold Box deal of the day over at Amazon today is Friends – The Complete Series Collection DVD box set for only $114.99 (that’s 62% off the list price of $299.98).

This is a 40-disc DVD collection contains all 10 seasons of the popular NBC sitcom that aired from 1994 to 2004 and has remained on television thanks to major syndication runs. Friends showed a group of 20-something friends — Rachel, Monica, Phoebe, Joey, Chandler, and Ross — living in New York City going through all kinds of real-life ups and downs with relationships, jobs, money, and friendship, all to humorous effect.

The six major stars — the “friends” — were played by Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt LeBlanc, Matthew Perry, and David Schwimmer, but the series had many major guest stars like Aniston’s then-husband Brad Pitt, Bruce Willis, and Danny DeVito, along with a reoccurring role by Tom Selleck as Monica’s older boyfriend.
