Shades for wall lamps can be as inexpensive as about $7, as listed on the Walmart site; they increase in price depending on size, material and complexity of design. According to the Shades of Light site, wall lamp shades range from about $40 to about $145.
Wall lamps come in two basic designs, shown on both Walmart and Shades of Light sites: mounted flush to the wall or on a swinging arm, a style that can accommodate more shade shape variations and give a customer more options. While the Walmart site lists a small number of round or "drum"-type shades priced between $8 and $20, Shades of Light expands the selection to include not only drum shapes but squares, bells, cones and flares. Less pricey choices from Shades of Light are simple paper cone shades, which average from $35 to about $65, while shantung silk shades, pleated burlap or other custom fabrics cost $80 or more.
