Geeze man, Crucial already gives you FREE 2nd-day shipping and you want it to be cheaper? They make some of the best memory and you'd be hard-pressed to find a better deal on DDR RAM, for example. You can find the cheapest priced DDR RAM on Pricewatch (MT chips, but generic PCBs) and think you're saving a few dollars (perhaps a whole $5) and then after paying shipping it's even MORE expensive than Crucial, which gives you premium chips and PCBs. Need I say more?
I've ordered RAM from Crucial a few times. They always give the 10% discount for ordering online and even when they aren't offering free shipping, their freight charges are very reasonable compared to the competition.
