Costway is showing an extra 40% off sale products with a code, and that code at the top of this page is best for you when the items in your cart are already marked as sale. The extra 40% off sale code applies only to sale products online, so it gives the biggest savings on reduced furniture, home and garden goods, hardware, sporting equipment and toys that are flagged as on sale.
Small non sale baskets under $300. If your cart is mostly regular price items and totals less than $300, the $40 off orders over $300 code does not apply. Use the 5% off home and garden furniture code only when you are buying furniture or covered appliances; for a $250 furniture order a 5% code saves $12.50, which beats getting nothing on non sale items.
Spending $300 to $399 on regular price items. If your full cart is not sale priced and reaches $300 or more, the $40 off $300 code is the clear choice for general merchandise. For example, on a $350 regular price order the $40 off code reduces the total to $310, saving $40. The extra 40% off sale code cannot be used unless items are on sale, and the 5% furniture code saves less ($17.50 on $350) unless your cart is exclusively furniture.
Spending $400 and above on regular price items. For a $400 plus non sale cart, the Fall Sale $45 off $400 code (when active) gives a bigger fixed saving than the $40 off $300 code. For example, on a $450 regular price order the $45 off code reduces the total to $405, saving $45, while $40 off would save $40 and 5% off furniture would save $22.50.
Buying sale items. If the products in your cart are marked as sale, the extra 40% off sale code at the top of this page normally saves the most. For example, on a $350 sale order the extra 40% off code cuts the price to $210, saving $140, which is larger than any fixed amount code.
Big spend choices over $500. When you spend over $500 on selected items you may be offered either a free fan or a discount coupon; the deal terms say choose either the free fan or a discount coupon. If the free fan is valuable to you, pick that option; otherwise compare the dollar value of the coupon to the fixed discounts above.
Our records show the 40% off percentage codes are rare, with the biggest percentage code in the 12 months to October 2026 being 40% off. In the 12 months to October 2026 we listed 63 offers for Costway (35 codes and 28 sales), and our team ran 35 checkout tests across 34 offers in that period.
When deciding, do the math for your exact cart: if items are sale priced use the extra 40% off sale code at the top of this page; if not, take the fixed $45 off $400 when your non sale total is $400 or more, or the $40 off $300 when your non sale total is between $300 and $399. If you have only furniture, compare the 5% furniture code to the fixed dollar offers and pick whichever leaves the lower final total.
