The receipt is typically from the merchant, not the dev, it should be in your email after purchase.
License transfer is answered in this thread. He does them manually, expect to wait several weeks. With a plugin that costs less than some companies' license transfer fee I'm surprised he does them at all. Why doesn't the new owner just buy it for himself and support a niche product by a small developer? To think of all the crap we pay $30 and more for, and then it's on 'labor-of-love' stuff like this that people want to save a few bucks? But maybe that's just me.
He's obviously a busy guy, he's apologised in this thread for his lousy communication as recently as October last year. That's not to say that he really could and should do better, but with a quality product like this and a ridiculously low price and no notable issues, I'll take it. It sure beats him not releasing it at all.
No offense to anybody, seriously. I just feel you're really missing out on something great and $30 is just not enough to hold back over just because he's slow to answer inquiries. It's like eight Granites rolled into one.
