Hi Don,
I believe you do have to add the charge for the embroidery (I did the same while ordering a jacket). You've probably already figured out that only some hats are available in a quantity of one. For any questions about the store, you probably want to e-mail Accurate Impressions (the company that does the imprinting) to be sure. Try
sales@accuratei.com or 925-600-1234. Hope that helps!
