To the tier 4 law student who googled "does ucc article 2 allow restocking fees":
-it's not that long. Read it. Want to borrow my print copy?
-the Best Buy situation (I know you're not googling that question randomly) involved merchandise that was not defective in any way, nor short of any warranty of fitness for a particular purpose. Some moron bought something without knowing what it did, and decided to whine on the Internet about how he's a fool. So, no, I am pretty sure the UCC does not allow people to void contracts where they get exactly what they paid for. Otherwise...
-...couldn't Best Buy just come to your house and say "Yo, we're here to return your cash. We decided it really didn't serve our purposes and we'd like to return it for a full refund of the GPS we gave you. Thanks."
-how is that D in Contracts treating you?
