Organic Egyptian Cotton Queen Sheets Sets $39.99 Shipped

Looking for a new sheet set? Amazon has 500 Thread Count Egyptian Organic Cotton Sheets for as low as $39.99 for Queen beds. 

Shipping is free with super saving shipping (orders over $25).

These kind of remind me of the sheet sets at Restoration Hardware, but for a fraction of the price and organic cotton. I wonder if they are comparable.

Thanks, Budget Savvy Diva!
