4AllMemory differs in their memory pricing for the Apple MacBook 13 inch, as they list their memory as individual modules. As this model of MacBook Pro requires memory to be installed in pairs you’ll have to do the math and order two.1GB memory modules are priced at $49, while 2GB sizes are $59, adn lastly the 4GB modules are really pricey at $569.00 each.

As you can see from the above pricing the sweet spot  for Apple 13 inch MacBook  memory upgrades at this time is the 4GB size with the cost being less than $100. If you need 8gb it will cost you for now. Always be sure to check the vendors sites for current pricing as prices could change at time of writing.
