Just Blinds is running a Spooky Sale with a 20% off sitewide promo code at the top of this page, and that is the lead offer to use for most purchases where a code applies. That 20% off sitewide is best for straightforward orders of one or two items that are not part of the selected products sale or a multi buy, because it reduces the full cart total instantly. If you are buying multiple items and can hit a multi buy or selected product discount, one of the other deals may save more.
Small orders under $200: Use the 20% off coupon at the top of this page. On a $120 order, the code takes 20% off, leaving $96 and you save $24. Free shipping also applies to everything, so you pay no delivery charge.
Orders of $200 or more but not qualifying for a free item: Compare the 20% code with the $20 newsletter signup credit. If your order is exactly $200, the 20% code gives $40 off, taking the total to $160, which is better than the $20 signup credit. The newsletter credit only applies to orders of $200 or greater, so it is only competitive on low four figure carts where an extra fixed $20 might matter for specific rounding or exclusions.
Buying four items of similar price: The Fall Back Sale buy three get one free is likely best when you are purchasing four items of equal value. For example, four blinds at $150 each total $600. With buy three get one free you get one $150 item free, so you pay $450 and save $150. Using the 20% code on the same $600 cart would take off $120, leaving $480, so the buy three get one free saves more on this basket.
Buying selected sale items: The up to 30% off selected products can beat the 20% sitewide if every item in your cart is in that selected range. For a single selected blind priced at $500, 30% off reduces it to $350, a $150 saving; the 20% code would reduce it to $400, a $100 saving. The 30% sale only applies to chosen items, so check which products are included before assuming it will apply to your whole cart.
Delivery and combination rules: Free shipping applies to everything, so account for no delivery charge on any option. The buy three get one free and the sitewide code both require a code to redeem; the sale that gives up to 30% off lists a promo code at checkout for those items. If terms for combining codes are not stated on the product page, treat the offers as separate; do not assume they stack.
Against our records, a 20% off code is the typical percentage we have seen in the 12 months to October 2026, and the biggest percentage code then was 30% off. Our team ran 33 checkout tests across 32 offers in the 12 months to October 2026, so codes and sales are frequent. Take whichever option leaves the lower final total for the exact items in your cart.
