Pyrex Drinkups

This cup is the hard to find 12 ounce size. Drinkups are featured on page 145-46 of "Pyrex the Unauthorized Collectors Guide" 2nd edition. I do not find any chips, cracks or breaks. I have several 12 ounce as well as 8 ounce ones available and priced individually. There is one 12 ounce in ivory also for sale. I need your zip code to calculate the postage.
