MacBook Pro sale ends tomorrow...
I'm new to the Mac world but have finally decided to dive in with a new 17" MacBook Pro. Best Buy is offering ~$200 off list but only with 4MB RAM. Can I bump this up to 8MB after my purchase? And if so, will I pay a premium for buying the additional memory after the fact (ie, more than I'd pay if I bought the MacBook originally configured with 8MB)? Do I have to go to Apple for intillation and would there be a fee? Also, are there any advantages to buying directly from Apple as opposed to a 3rd party? The sale ends tomorrow (6/2/12) so quick responses would be greatly appeciated.
MacBook Pro, Mac OS X (10.7.4)
