Ending today, Cost Plus World Market takes 20% off sitewide via coupon code "HOLIDAY" as part of its Cyber Monday Sale. (Discount is applied in-cart.) The discount even stacks with sale items. That's the largest coupon we've seen from this merchant since March, when we saw 25% off. Shipping starts at $4.95, but orders of $150 or more bag free shipping. Sales tax is added where applicable.
