I only buy a few DVDs, books, CDs or video games online a year - and that's only if it's cheaper/more convenient than buying the particular item offline.
I like to browse online for good prices on e.g. CDs, DVDs or video games, though. But the truth is that it's often either the same price or cheaper to buy it offline, so that's what I mostly do.
I like shopping in actual stores, but I also like shopping online for some things (as said).. so I might get more into online shopping in the future.
