I always will check out a couple of sites first before buying anything online - you can usually find coupons and, every once in a while, actually find what you are looking for at a really good price. It's not good to do what I do and check them every day, however - you just end up buying awhole bunch of junk. But here they are if you're interested:
- Spoofee - great deal site that has a lot of tech items but also other things as well. They also have a tab to go to coupons for different companies.
- TechBargains - kind of like Spoofee, but a little more focused on tech items.
- Fat Wallet - they have tons of postings, but it takes a little while to find stuff, unlike Spoofee or TechBargains, which is laid out a little better. The best thing about Fat Wallet is the cash back - you create an account and if you use their links, you'll get a percentage of your purchase price back (the percentage varies from store to store).
- If you use Google Desktop, create a tab called Deals - it will automatically grab a bunch of deal sites like Spoofee and TechBargains and put feed boxes for all of them - you can't get easier than that.
