Discount window blinds can be found at wholesale shops and outlets. Buying in bulk can usually save money and most wholesalers will give you a larger discount the more sets of blinds or shades that you buy. If you are purchasing multiple window coverings for an entire house or office you will probably get a better price than if you were just purchasing a single window treatment.
Another suggestion is to hit the newer retail stores that are trying to get established. They will typically have low prices and have certain discount window blinds and discount window shades in their showroom. The store may give you a discount just to win your business. If you do your homework and shop around for the best prices you are sure to find cheap window blinds and discount shades for your entire window covering needs.
