The W Store knocks 40% off most items sitewide via coupon code "KL7M5". Even better, that stacks with sale items, which are already marked up to 83% off. That's tied with our February mention as the best percent-off coupon we've seen from The W Store this year. Shipping starts at $7.95. The W Store is the storefront for W Hotels and sells apparel, accessories, and bedding. Deal ends May 21.

A best bet is the W Hotels King Size Wildflower Duvet Cover in Glacier Blue for $204.99 before coupon, $122.99 after. With $16.95 for shipping, that's $152 off and the lowest total price we could find.
