I did the same as spyhunter (except I had a Sony Style gift certificate). I figured the certificate made the RAM more reasonablly priced, and I would never get a hassle from Sony should my lappy need warenty service. But in retrospect, they just want too much for the memory. You can get brand new quality (brand name) memory for much less. There are already plenty of threads in this forum about where to get good prices, and what type of memory you need.
