Lumisol Celestial Series solar light set

I am looking to purchase a quantity of 3 "Lumisol Celestial Series solar light set."

I bought my set at my local Costco Warehouse, and liked it so much that I went back to purchase a few more for Christmas gifts. (However, my local Costco was out of them.)

This product is available on Amazon, but the price and the S&H is way too high.

I would definitely want an option to add USPS insurance at the applicable rate because these items include fragile glass.

Thank you!
