DVD Storage

Apologies if this has already been covered, but my sheer laziness stops me from hunting through the threads.
Like many people here no doubt I have lots of DVDs, about 300-400.
But how to stote them?
I rent a flat, and therefore am unable to put up shelves, the most convienent way. So does any one have any suggestions as to suitable storage methods.
Most places I've looked (Argos/Ikea) have units that either hold too few (I really dont want to go out spending too much and dont have the space to buy numerous multiples) or are suitible for holding lots, but are meant as bookshelves and so too deep.
Your help is appreciated.

 

Argos and IKEA are your best bets unless you have lots of money to play with.
There are some good suggestions in this thread - hopefully you can summon up the energy to read 4 pages
