I bought 2400 points and all of the codes worked - one thing nobody has mentioned yet is that they aren't just Wii Points codes, they're Nintendo Points codes. That means they work on Nintendo DSi too! Since he sends multiple codes worth 200 points each, you can split them among your two systems, if you have both. Very nice.
Even at 2:30 AM eastern, he still sent the codes in less than five minutes. Now that's service. Thanks again jaksapple!
