Before You Buy at The Sill
What shoppers ask most about The Sill.
›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.
