So I googled this and apparently, apple's official rule is the 14day return with 10% restocking. However, some people were given the opportunity to upgrade within 30 days, no restocking free.. Store manager discretion, so I guess I have to talk to the manager if they give me a hard time!!
Good luck. I finally talked my Mother-In-Law into trading in her Dell and bought her an Imac on Sunday. I have looked over the upgrade and decided that for what she uses the computer for she will never notice the difference.
