Best Adult VOD Site?: The most popular VOD service in our guide is Hot Movies, which has tens of thousands of adult titles. You can buy access by the minute (at 8 cents and up) or purchase unlimited viewing of any individual title for two, seven or 30 days. Our most popular flat-rate site is Video Box, which charges $9.95 per month for unlimited downloads from its library of more than 3,000 movies.

Prefer to Rent DVDs?: If you prefer to rent DVDs rather than download movies, compare online services at our Adult DVD Rental Guide. Most charge $10 to $30 per month to have one to three adult DVDs out at a time, with no late fees or return dates. A few rent individual DVDs for $3 to $5 each per week. A credit card is required to join any DVD rental service.

Discount Adult DVDs: If you're looking for bargains and selection, we suggest Movies by Mail, which offers new customers a free movie when you pay $4.95 shipping, as well as discount codes (see site), XRent DVD, which sells ex-rental titles from $4.50 each, Overstock DVD, which offers clearance titles and free shipping, or Wanted List, which offers 10 percent off any $25+ purchase with the code ADULTDVD10%OFF or free shipping with 5PORNSHIP.
