You do not have to be a paid subscriber to buy any items.
All used items come with the original case, inserts, and the discs have no rental stickers on them. The case and inserts will look like new.
If the title originally had vouchers / codes for digital redemption, those will be included as well.
Sort by DVD / Blu-Ray and price if you like.
I'm not sure they've ever had this promo before.
EDIT - Pairing this with the Groupon [groupon.com] deal for a free month trial of 2 rentals out at a time per month and a $5 coupon - you can get a movie as low as $0.99 plus tax. The Groupon deal requires that it's a new account.
