I was tired of my compute running so slowly that I bought another GB of RAM (upgrading from just 512 MB). I used MR's Guides on purchasing RAM to scout out some websites, then I found what I needed and decided on Crucial. My GB cost about $112 whereas the next cheapest was $110 + $6 shipping. I chose free shipping from Crucial's site and actually received it yesterday, approximately 24 hours after purchasing it. Yes, I got express mail for free. I'm not sure if this is customary or an accident but if it were eBay I would definitely give Crucial 5 stars.
