National chain Redbox has kiosks in nine local Walgreens (check redbox.com for locations), but Blockbuster is countering hard: 200 Express kiosks inside Duane Reades by year-end. The ATM-like machines will hold approximately 900 DVDs, each available for $1 a night and returnable to any location (blockbusterexpress.com).
