Step1
Go used. Check out the local garage and flea sales for used DVDs.
Make sure to inspect the disks for scratches or other flaws, and if
you're a purist make sure the DVDs haven't been sitting out in the
sun. If they have, the box art could be faded before its time.
Step2
Use the Web: Every other site is selling DVDs now, but a few offer
very good deals on a consistent basis. Try Amazon.com's DVD page for
regular bargains, Overstock.com and eBay or half.com for used DVDs.
Bargainflix.com compares and contrasts the best online DVD prices,
which saves you a few steps.
Step3
Local DVD shop. Used DVD stores can be found in most communities,
and they offer some great prices on DVDs. Most will visually inspect
the DVDs they buy to make sure they're scratch free. And since DVDs
are less prone to image disintegration than VHS tape, you can watch
and savor your used DVD for the foreseeable future. Be careful to
avoid buying "full screen" DVDs, which don't offer the same visual
presentation as "widescreen" versions but may sell for a lower price.
Step4
Swap with friends. You've watched your DVD of "The Princess Bride"
more times than you can count, but perhaps your friend hasn't. Try
posting an advertisement on your city's Craiglist.org page to find new
swapping partners.
