We have excluded our limited edition special collab products from qualifying for our WELCOME10 discount specifically because it benefits you more when a discount is not applied.  99.9% of customers that purchase a collab item, buy 1 item on their order.  The 10% discount for first-time customers would give you a ~$6.60 discount on the collab deals, but consequently, it would thereby disqualify you for free shipping.  Due to increasing freight costs, it is actually a much better deal for you to have free shipping on these styles.  You can save your WELCOME10 discount code to use on a later purchase.  Thank you kindly for your interest in our FreewatersX Exclusive Collab Projects!
