If you are any kind of techno geek, you MUST go to Fry's.
They even have one in San Jose.
http://shop2.frys.com/isp/sanjose.htmlIts like.... costco, but ALL computer stuff. (gadgets included.)
When I'm there, I'm like a kid in a candy store. Most stuff, even after you convert the price (and accidentally remove all your receipts and prices, claiming that you brought it all down with you so that you dont have to claim it at customs) will STILL be cheaper than getting it up here.
Check the local papers. Once a week, they have a full page ad of their sales for that week (sometimes, sale of the day)
