Does an apple store has 8 gb RAM readily available in the store so that I can purchase it and upgrade my RAM from 4gb to 8 gb?
TTBOK the Apple Store will not upgrade RAM for you.
You can call them and check to see if your local Apple Store might be willing to do it.
If they have a technician free to do so, and the MacBook Pro can be upgraded. What year/model MacBook Pro do you have as not all can be upgraded.

Make a Genius Bar appointment and take it in and see if they will add the memory for you - you will have to purchase the ram from the Apple store, not bring in your own.

You will see that it is an easy installation which you can do yourself. Much less expensive if you do it yourself.
The best Mac compatible RAM can be ordered from OWC or Crucial.

It is extremely easy to install the ram. Check out ifixit for repair guide, read thought it a couple of times.
