USCF Sales is running a National Chess Day sale and the lead deal is the 25% off voucher at the top of this page, which takes 25% off orders over $250 and is best if you are placing a larger purchase. It needs a checkout promo code and a minimum spend of $250, so it makes most sense when your cart is well above that threshold.
Under $150: use the 15% off orders under $150 code. For most carts below $150 the 15% code saves more than the newsletter 10% signup, because 15% is larger. On a $100 order, for example, the 15% code takes 15% off ($100), leaving $85, so you save $15; the 10% newsletter would leave $90 and save $10.
$150 to $250: use the 20% off code valid for orders between $150 and $250. It beats the 15% sitewide code for the same cart size. On a $200 order, for example, the 20% code takes 20% off ($200), leaving $160, a $40 saving; the 15% sitewide code would leave $170, a $30 saving.
Over $250: use the 25% off voucher at the top of this page. For carts above $250 that code gives the biggest percent saving on full price items. On a $300 order, for example, the 25% code takes 25% off ($300), leaving $225, so you save $75; the 20% code would leave $240, saving $60.
Buying sale or clearance items: clearance and software sale items are already reduced by up to 66% or up to 60% and those markdowns apply to sale product pages. The up to 66% clearance deals can beat the percent codes on individual sale items; compare the final sale price to the price after any sitewide code. The free shipping over $100 rule excludes Clearance, Shopworn, Imperfect, or Otherwise Marked items, so a large cart of clearance stock may not qualify for free shipping even if it totals over $100. Media orders over $25 qualify for free ground shipping separate from the $100 rule.
First time customer or small purchase: the newsletter signup gives 10% off and is useful if you cannot meet the $150 threshold and do not want to use the 15% under $150 code for any reason. The newsletter offer is only for signups and is not the page lead.
Our records show 77 percentage codes listed in the 12 months to October 2026, the biggest was 30% off (November 2025) and the typical code was 20% off. In the 12 months to October 2026 our team ran 75 checkout tests across offers and kept screenshots for 45 of them.
When choosing, calculate the cart total with each eligible code and take whichever leaves the lower final price. Only apply a single promo code at checkout unless the terms on USCF Sales say otherwise, and remember that sale product prices are already reduced so a code may not improve a clearance item further.
