Through 10/10, Amazon has dropped these 1200 Thread-Count Royal Heritage Cotton Sateen Sheets to $79.99, the lowest price I've ever seen for 1200tc sheets. The 100% cotton sheets have a glossy sateen weave, come in 5 colors and either King or Queen size. Even better: spend $125 and use their $25 off coupon code. Shipping is free; there is no sales tax (except KS, ND, WA).
