Just so I understand and don't screw things up, am I understanding this sale correctly:
When the sale is open, go to the store and add however many of whatever caps you want to the cart.
There will be a place for notes, so we can note, for example, that you want up to 3 caps in any style, with a few of your top choices.
Check out? And then it won't charge you, because we'll get invoices later?
