Tanga offers the Pure Garden Interlocking Floor Tiles 6-Pack in Terracotta for $14.99. Coupon code "DEALNEWS" knocks that to $13.99. With free shipping, that's $3 under last week's mention and the lowest price we could find now by a buck, although most retailers charge at least $20. Each plastic tile measures 11.5" x 11.5" x 0.5" and features an openwork pattern to provide water drainage.
