Just saw a note that Crucial is offering 5% off memory upgrades. These things are usually on a limited basis but there was no mention of when the deal would expire, so it looks like it runs until they say it doesn't.

Checking it out I noticed that they are also offering free shipping (5-9 business days USA only) for a limited time. ... Which these days might be worth more than the actual ram.

Memory is quite often the cheapest, easiest and most effective upgrade you can add to your system and Crucial is about the easiest place on the planet find exactly the type your system needs. There's a drop down box for those who know the PC / Laptop model or you can use Crucial detection software. (Click Memory >> System Scanner)

So if you're in the marketcheck out the deals here.
