Special Offers
Each month Seido sets up new special offers: here is your chance to get your new equipment at an even better price! We, however, never offer very extensive discounts. This is because we believe that if a product can be discounted 20 or 30%, this is because its simply overpriced. Made in Japan items have a small turnover, our products can withstand years of practice, and we do not wish to push you buying things you don't need.
We however offer discounts for bulk orders, according to what we can save in order preparation and shipping fees. If your order is eligible to a discount (order over 60,000 YEN with 5+ tangible products), an invitation to contact us will be displayed in the shopping cart prior to checking out.
