You're lucky! I was sent a few LESS than what I ordered (from Discountmugs.com) and now am short And they wouldn't send me the amount I was short by, only a partial refund. The cost they quoted me to re-order for the few missing was ridiculous and just wasn't worth it.
I had a terrible experience with them, but I'm glad to hear that maybe they've smartened up and now over send rather than under.
Sorry for the rant, they're SUPER cute!!
