Saw these at my local Costco in Irvine for $18.97. I bought some 2 weeks ago at the same location for $24. Going to get a price adjustment. It may just be a store specific price drop--but this is not a coupon or sale. And they're still $33 online.
They're great. Attached some tan ones to the top of our pergola and makes it really nice without blocking all the light.
