Bracelet? I think you may have had an autocorrect thingy - if this is helpful, all of their rotating drafts have all sorts of different prices per ounce pour.
That will depend on what you end up drinking. We don't pre-charge. That 40oz is the initial capacity you are given. Our beers and wines range in price, and the cost per ounce is listed on all of the illuminated boards above their taps. You only end up being charged for what you consume, so it's not a "use it or lose it" situation.
