I never actually bought a computer. They were usually "hand-you-down/used" computers, or given to me as gifts from my older sister and parentsor from volunteering at a computer recycler for 24 hours.
I believe my sister bought the PCs from a local "Mom and pops" style PC store and Best Buy's Online store.
All my PCs still work except for the 200MHz Pentium 1 with 64MB of RAM. The 3GB hard drive crashed...
It is strange, but PCs and TVs are one of the expensive things I don't buy since I'm so used to getting them for free from people who buy them for me or just give me their old PC when they buy a new PC.
