Miko currently has a 15% off coupon code at the top of this page that also adds free shipping, and that is the lead offer to try first for most purchases. It applies site wide to robot toys, STEM kits, wellness devices like foot massagers and air purifiers, and is best for baskets where free shipping changes the total. The other active codes are two further 15% off coupons that target selected products and come with standard site terms.
Small orders under $50: the free shipping in the 15% off coupon at the top of this page matters most if you normally pay for delivery. Use the 15% off coupon with free shipping. For example, on a $40 order the code takes 15% off, then free shipping applies, so you pay $34.00 and save $6.00. The selected products 15% code may not include low priced items, so prefer the lead coupon.
Mid sized orders $50 to $200: the 15% off coupon at the top of this page with free shipping is usually the simplest choice because it applies broadly and removes delivery cost. If the item you want is specifically listed under the “15% off selected products” offer (for example certain foot massagers or the Ibuki Air Purifier), you may use that selected products code instead, but note its terms say it cannot be used with other codes. Use the selected products 15% code only if the product is named in that offer and you do not need any additional codes.
Larger orders over $200: the lead 15% off coupon with free shipping still takes 15% off the whole order and removes delivery, so it remains competitive. Both other 15% codes give the same percentage but the second 15% code is marked “selected products only,” and the third 15% code explicitly forbids combination with other codes. If you have a mixed cart of items where some are not eligible under the selected products code, the top 15% plus free shipping is the better pick.
Buying a named wellness device or a specific foot massager: the “15% off selected products” code names the Ibuki Air Purifier and specific foot massagers (Masuta, Yoisho, Yugen). If your cart contains one of those exact models and nothing excluded, use that selected products code; its terms also say one discount code per order.
Newsletter signup: the newsletter signup is a way to get special offers later but is not a headline coupon and should only be considered if you want future promotions; it does not replace the current 15% codes.
Our records show 79 percentage codes in the 12 months to October 2026, with the biggest at 20% off and the typical value 15% off, and our team tested 80 Miko codes at checkout in that 12 month window. That means 15% codes are the pattern and the one on this page is in line with the usual offers.
When choosing, compare the total after the discount plus any delivery you would otherwise pay and take whichever coupon leaves the lower total. Use the top 15% coupon with free shipping if delivery cost matters or your items are not limited to the selected list; use the selected products 15% code only when it explicitly names the product you are buying and you will not try to combine codes.
