The 20% off sitewide promo code at the top of this page is Half Price Drapes's lead offer and is best if you want a simple, sitewide cut on regular priced items and sale items, provided you use a single promo at checkout. It takes 20% off whatever you buy, but the code cannot be combined with any other offer. Use it when you want the single biggest percent off without hunting for a specific sale item.
Small orders under $100: For a modest purchase, the 20% code usually gives the biggest straight discount. On a $80 order, for example, the 20% code takes 20% off, leaving $64 and you save $16. If the item is already in a marked sale where the price is reduced by more than 20%, the sale price will be lower than applying the code, so pick the marked price instead. The 15% and 10% promo codes only help if you cannot or do not want to use the 20% code.
Mid size orders $100 to $300: The 20% code still tends to win. On a $200 order, the 20% promo code reduces the total by 20% to $160, a $40 saving. If the product you want is in the 55% or 50% off designated sale lines (custom curtains, Roman shades), those marked sale prices beat the 20% code. For example, a custom curtain listed at 55% off is cheaper than applying a 20% code to the original price.
Large orders over $300: Check product level sales first. The fall sale offering up to 60% off curtains and the 55% off custom curtains or Roman shades will save more on eligible items than any promo code. Use the 20% promo code only if your chosen items are not included in those marked sales.
Buying custom curtains, Roman shades or marked fall sale items: If the product is specifically listed in the 55% custom curtains or 55% Roman shades deals, those fixed sale prices generally give the biggest saving. Those sale discounts are not compatible with other deals, so the 20% promo code cannot be added to a 55% sale price.

Our records show 28 offers for Half Price Drapes in the 12 months to October 2026, split evenly between codes and sales. Percentage codes in that window ranged up to 25% with a typical code of 15% off, and our team ran 14 checkout tests across 14 offers in the 12 months to October 2026. That history means the 20% promo code is larger than the typical code but below the biggest past code of 25%.
To choose between these options, compare the final totals: if the item is in a marked sale at 50 to 60% off, buy at the sale price; otherwise use the 20% promo code at the top of this page. Do not try to combine the promo codes with the brand sale discounts because the codes state they cannot be used with other offers.
