Is The Sill Black Friday & Cyber Monday 2026 Worth the Wait?
Black Friday lands on November 27 and Cyber Monday on November 30. Will The Sill drop new codes? We add them the moment they appear.

new codes
Why so few shoppers: we only count a shopper when we saw their cart total drop as the code went in, and most checkouts happen where we can't see them.
Will The Sill have Black Friday codes this year?
Very likely. The Sill published 1 code in last year's Black Friday week alone. We add new ones here the moment they appear.
Do people actually save at The Sill on Black Friday?
Yes: 2 shoppers saved with a The Sill code in last year's Black Friday week, $46 between them. The count is small because we only include shoppers whose cart total we saw drop when the code went in, and most checkouts happen where we can't see them.

The Sill Code Checks, Day by Day
Every The Sill code check from the last 12 days, plotted by the day it ran. Green is how many came back working. Red is how many thesill.com would not accept. That is the checkout testing you did not have to sit through yourself.

where this data came from:
6 automated cart runs1 web search results
Last confirmed working on . Codes that stop clearing get pulled off this page automatically.
Why so few checks: a code is only checked when a cart reaches thesill.com's checkout, so a store with fewer shoppers or a quiet stretch produces a thin window. Read these figures as an early sign, not a settled rate.
What These Numbers Mean
A code check is one result for one code. Most are our agents applying it to a real cart and reading the order total before and after; the rest come from tracked orders and from shoppers reporting back, as broken down above. Worked means the code was accepted and the total went down. Would not apply means thesill.com refused it on that cart. That is not the same as the code being fake. The usual reasons are:
- It expired or the store switched it off after it was published.
- It was single-use and had already been redeemed.
- It only covers certain categories, brands or individual products.
- The cart did not reach a minimum spend.
- It is limited to new customers, a first order, or an email sign-up.
- It cannot be combined with an active sale or another code.
- It is tied to a different country, currency or membership.
So a code that failed one check can still work on your cart, and the success rate (checks that worked divided by all checks) is best read as how easily The Sill discounts apply in general, not as a verdict on any single code. Hover any bar in the chart to see that day on its own.

Before You Buy at The Sill
What shoppers ask most about The Sill.
›Do The Sill promo codes work today?
Possibly. A code worked at the The Sill checkout 2 days ago, but none of the codes listed now has been confirmed in the last 14 days.
›Can promo codes be applied to digital gift cards or past purchases?
Discount codes cannot be applied to digital gift card purchases or retroactively to orders placed before a sale began. Additionally, third-party artisan items and select clearance inventory are excluded from sitewide coupon promotions.
›Do you offer price adjustments if an item goes on sale after purchase?
If you purchased a full-price item and the price drops within 3 days of purchase, you can contact customer support to refund the difference. Items originally bought at a discount are ineligible for price adjustments.
›Can multiple promotional discount codes be stacked on a single order?
Only one promotional code or discount voucher can be applied per checkout transaction. Promotional coupons also cannot be combined with items already marked down on sale or promotional bundles.
›What happens to plant orders placed during freezing winter weather?
To ensure plants arrive healthy, orders headed to states experiencing freezing temperatures may be held up to two weeks until weather warms up. Orders are then expedited with protective sleeves and heat packs.
How We Verify The Sill Codes
Nothing goes up here on trust. A The Sill code is collected, applied to a real thesill.com cart, dated the last time it took money off an order, scored on what came back, and pulled once it stops clearing. Promotions have no code to run through a checkout, so those are dated when they go live and dropped when they lapse. Here is how far that has got on this page, and every change the agents logged along the way.
