DecorateToday.com has a great selection of blinds and window coverings. They offer "Free UPS ground Shipping", "Lifetime Lowest price Guarantee", and "100% Satisfaction Guarantee". This company has been in this business a long time and have been also doing mail order for years, so they really got this business figured out.

   BlindsWholesale.com also offers a great selection of window coverings and great prices, but their site is a little more cumbersome to navigate. If you are patient you can find some great deals here.
