I find RAM prices are so much cheaper at US online stores than Canadian stores. Especially today with our dollar at par. Did you pay DUTY on memory purchase from US online store? I find it is cheap to buy RAM from OWC 4GB PC5300 DDR2 667MHz DIMM Upgrade Kit $199.00USD + Shipping $20.40USD. Lifetime Advance Replacement Warranty. Canadian Online stores can't beat that anywhere. Does anyone know a Canadian store that beats that price?
