"To celebrate, we're giving away fifty copies to anyone who enters this drawing."
Okay, so, let's look at this copy, which is encouraging me to click on a link, enter my name and email address, and possibly sign up for a newsletter or three.
I understand the goal of this exercise.
The wording, however.
What that copy actually says is, "if you give us your information, we will give you 50 copies of this book." giving away fifty copies to anyone. - the "fifty copies" go to "anyone" so that's fifty copies to each person who enters the drawing.
(you keep using that word. I don't think it means what you think it means.)
Pretty sure that's not what they intended to say, and clicking through to the entry, we learn that, no, not anyone, only those in the United States, and no not fifty copies each, there are fifty copies total to be sent out.
Yet, wording is everything. One could argue false advertising with the current phrase order.
That whole "eats shoots and leaves" thing in a different format.
