Note to the wise:
If you are sending out promo material for your book, proofread. And proofread again. And a third time. Then have a very picky friend proofread.
Do not ask me to buy your book if there are grammatical mistakes, misspellings, and punctuation errors in your solicitation. I not only will refuse to buy your book, I will send your solicitation to Theresa, who will make fun of it (just with me).
We're nice. We don't go on Twitter and tweet about each mistake. Others might not be so kind.
I have been getting a whole lot of "buy my book" solicitations lately, and so this is a frequent annoyance.
