Each coupon code is a unique and customized number comprised of letters and digits – they are programmed for one-time use so be careful when using them. We suggest you complete your transaction in one session and not to “time-out” and resume some time later. If you run into a problem we can always offer you assistance – best way is to send us a text message at (212) 518-0600; email us at info@maide-z.com; or use the Contact form on our website. Of course, you may call us if more convenient and if we are not available to take your call then we will do our best to connect with you just as soon as possible.
