Hello robert shepherd, if you order them now (about 2 weeks making costume time) and use a faster shipping method (Express Shipping, 7-15 days shipping time), it will reach you around 22-28th May, 2015.
*All shipping information (including methods, cost & estimated delivered date) will be shown in order page, before payment; you can pay extra cost to upgrade shipping method there.
*Please remember to mark down the date (you need it) in the order form when you order it. :)
