Much thanks to the Popcorn Samurai for this item:

It's that time of year again, time for Deep Discount DVD's semi-annual 20% off sale! This is a great opportunity to fill holes in your anime collection, as well as pick up lots of DVDs for cheap.

The sale runs through November 18th has been extended until November 23rd, and you need to use one of these coupon codes to get the 20% off:

DVDTALK
ESPN
NYTIMES
SUPERSALE
USATODAY
YAHOO

Each coupon can only be used once. It's also worth noting that posters and storage accessories are also included in this sale. Maybe it's time to pick up that giant DVD rack I so desprately need.

I suggest concentrating on box sets. With this sale you can get some excellent deals.

I'm not affiliated with this site in the least, I just wanted to bring this great sale to everyone's attention. Have fun guys!
