Yaasa currently runs an Up to 30% Off Sale Products event on the website, and that sale is the lead offer here. It is best for you when the items you want are specifically marked down in the sale collection, for example height adjustable desks and selected furniture for home or office use. The other active offer, up to 20% off ergonomic equipment, covers a different set of marked items and is also valid online.
Large single purchase on a marked sale product: If the exact product you want is in the sale and shows 30% off, use the sale price. On a $500 height adjustable desk, for example, the sale takes 30% off, so the final price is $350 and you save $150 (original $500, percent 30% off, final $350, saving $150). This is subject to stock availability and the product being explicitly in the sale.
Multiple sale items: If you buy more than one item that is marked down by 30%, the same percentage applies to each marked item as shown on the product pages. For two sale chairs listed at $300 each, the total before discounts is $600; with 30% off each you pay $420, saving $180 (original $600, percent 30% off, final $420, saving $180). Prices are as marked online and the discount only applies to items included in the sale.
Buying ergonomic equipment not on the sale: If the product you want is in the ergonomic equipment range but not in the sale, the up to 20% off ergonomic offer is the relevant one. On a $400 ergonomic chair that is eligible for 20% off, you pay $320 and save $80 (original $400, percent 20% off, final $320, saving $80). The ergonomic discount applies only to items listed as eligible and is shown on their product pages.
Mixed carts or uncertain markings: If your cart mixes sale marked items and ergonomic items with different marked discounts, treat each item by the price shown on its product page. Compare the final totals. For example, a $500 sale desk at 30% off plus a $200 non sale accessory with no extra discount becomes $350 plus $200, total $550. If both items were instead eligible only for 20% each, total would be $560 (original $700, percent 20% then 20% applied per item, final $560). Use the lower total.
When choosing, take whichever offer gives the lower final price for the items in your cart, using the prices shown on the site. Both offers are website only, and the sale is while stock lasts, so check the product pages for the exact marked discount before you complete checkout.
