Usually I post to ask questions so I thought I might try to help back with a deal.
4GB MSPD PLATINUM II LEXAR $15 after $17 rebate and you pay for shipping and tax (around $7)
Please note that this is today only as it's celebrating its Anniversary. About $20 for the 4GB stick. If you have a Fry's near you, these might be there too (save on shipping).
There's also some nice stuff at Fry's today, if you're interested in going/checking out other stuff, here's a link that compiled the good deals together. I'm especially liking the $10AR Antec 430W PSU. Enjoy
