...right away I got an email about a promotional credit that says:
"Congratulations! You've earned a promotional credit equal to 40% of the purchase price of your recent Kindle book purchase. You can see your promo credit balance on any Kindle book product detail page or see your credit applied at checkout when buying a print book. The credit will automatically be applied towards your next digital or print book purchase."
Did they just give me a credit for 40% off of $0.00 or am I reading that wrong?
