Maximize savings before you check out

So many ways to save, but usually you can use just one, so you better check which one is the best for you! Before placing your order, you can:

• check if a bundle price is already discounted,
• check if “Subscribe & Save” is available,
• then apply the best coupon code that still works with the cart.

Remember that some coupons and offers cannot be combined, so you should always check what is the greatest discount and how you can save the most before completing your order.

Common promo code problems (and how to fix them fast)

Before using a promo code, you should always check the terms and conditions. Any coupon has restrictions and limitations of different kinds, and if your cart doesn’t meet all the criteria, your discount code won’t work or will result "invalid". 

There might be some eligibility exclusions (so the promo code might be valid only on select items), time restrictions (the coupon is valid for a limited time only), a minimum spend might be required, and the promo code might be valid for specific customers only (such as new customers or members). Always check these terms before applying your coupon and everything will work just fine. Don’t forget to check also if there are any extra spaces or spelling mistakes: that might cause some trouble too!
