If you treated your MagSafe power adapter like an egg but the cord has frayed anyways, Apple may replace your adapter for free. Apple posted a Knowledge Base article about the replacement of frayed cords. Even if your product is out of warranty, Apple says you may be eligible for a free replacement if your adapter shows no signs of abuse. Read the KB article for all the details. Free sure beats the $80 it would take to buy a new one.
