The 20% off promo code at the top of this page is the lead offer from Koa Coffee. It takes 20% off online orders of regular items during the 29th Anniversary Sale and is best for a one time cart of full price coffee or accessories you want right away. The code does not apply to subscription orders and may not be combined with other promotions.
Small orders (under $30): the 20% off promo code will cut a small cart but the saving is modest. On a $25 order, for example, the code takes 20% off, lowering the total to $20 and saving you $5. Use the promo code at checkout if you are buying full price items and want an immediate discount.
Mid size orders ($30 to $100): the 20% off promo code usually gives the best straightforward saving on full price items. On a $60 order, the code takes 20% off, reducing the total to $48 and saving you $12. If the items you want are on the sale pages instead, check the sale price, because sale discounts can be much larger on marked items.
Big orders (over $100): the 20% off code still applies to full price items and scales with your cart, but sale items may deliver bigger savings for large spends. For example, on a $200 cart of full price beans the promo code takes 20% off, bringing it to $160 and saving $40. If those same items are in the sale at a larger percentage, the sale price could beat the code, but the sale only applies to marked sale products and needs no code.
Buying sale items: the Up to 72% Off sale applies only to products already marked as sale. Those discounts can exceed the 20% promo on the same item, so if your chosen coffee is on the sale pages, leave the code off and buy at the reduced sale price. The sale needs no code and applies site wide only as shown on each product page.
Regular deliveries and subscriptions: the up to 15% Off subscription deal applies to subscription orders and is separate from the promo code; the 29th Anniversary promo code explicitly does not apply to subscription orders. If you plan recurring deliveries, the subscription discount will usually save more than paying full price even with the one time 20% code, because the code cannot be used on subscription orders.

When you decide, calculate the final totals and take the lower one. Remember the 20% promo code cannot be combined with other promotions, so either use the code on full price items or buy the marked sale price or a subscription rate, whichever results in the lower total.
