Newbie Needs Your Help

This is not a reader question, but a blogger question, my own!  Please help if you can:

I just moved to a new area and have new stores around me.  Two of the stores are Rite Aid and CVS.  I need diapers for my 2 year old (potty traning where are you?).  Can you help me figure out some beginner scenarios at both stores that minimize out of pocket.  Where do you think I can get the better deal this week?

What do you think?  Can you help me out?
