Hints and Tips
COS Resell: Get more for clearing out your wardrobe by using the COS Resell platform. Partnered with ReFlaunt, this platform allows you to resell your pre-loved COS pieces easily so you can introduce sustainability to your wardrobe as well as earn money for your once-favourite items. Even though COS does take a commission of 10% from each sale, you can still make money to potentially put towards your next purchase.

When you do, you’ll receive a 10% COS promo code which you can use to save on your first order. You’ll also be the first to learn about the newest products, latest sales, news, and events.
Seasonal Sales: Regularly check the COS homepage to catch announcements about Wholesale Replica Bag seasonal discounts and offers. Typically active during Summer and Winter, we have seen savings of up to 50% off popular products. This is a great way to update your wardrobe with all this season’s must-haves while sticking to your budget.
