it's interesting that this thread has re-appeared. i just found out about crucial's sometimes strange pricing schemes this past week, and i figured it was an anomaly. i guess i was wrong.
i bought a SR MBP with 2 gb in september, and i decided to get my girlfriend 2gb for her old yonah macbook. i bought it from crucial (always trusted their RAM... and still do, regardless of what comes next), but returned it, realizing i could give her my 2gb of ram and get myself a new 4gb
so i put in my laptop info into crucial.com just for the heck of it, and it gave me a HUGE price for the 4gb kit! it was stated as containing 2x2gb sticks, but right there on the same page (listed all compatible RAM for my system) the single 2gb stick was less than half their 4gb upgrade kit.
to make matters worse, when i googled the product numbers to see if they were different, i came to see that the EXACT same crucial RAM can have completely different model numbers based on the retailer (even a completely different naming scheme...).
so after all this, i stuck to what i've been doing the last ~8 years, and bought from newegg. 2x2gb sticks of crucial ram for something like 150 bucks (before tax/shipping). got it the next day since i live in NJ, where newegg has a warehouse. automatic next day delivery for any method by paying sales tax
