Hello, I am going to Gaithersburg, MD (Washington D.C. area) this August. I am wondering where I could buy 2 GB of RAM for my MacBook, at a good price. I am from Canada, and I don't want to buy RAM from the USA and pay for shipping, duties, etc. from home. Any suggestions on where to buy it?? I might buy a BT mouse too (exchange rate is awesome at the moment!) If I do buy it there, I will put the RAM inside my MacBook before heading home. Thanks!!
