I like Esalerugs.

Hi Sushi--- you probably know but if possible it is suggested to order the smallest size available ( like if they have a 2 by 4 ) to at least see the colors. Then if it looks promising order the size you need. Returning a full size rug sounds like a major project to me.

Be sure to look at the fiber content. Many synthetics are photographed nicely but can be a bad surprise. Shiney, bad nap, cheap looking.

I'm in western Canada without any rug shops in the area, and have had good luck in the past year buying some wool rugs (tribal, Persian style) sight unseen from eCarpet Gallery's Canadian store in Montreal.

The last rug I bought from them was in November, a hand-knotted Gazni wool rug, about 9'6" x 10', which I bought for $1,000 CAN.

They always seem happy to do a deal, even by email.
