Walmart offers the Mainstays Room Darkening Solid Woven Panel Pair in a selection of styles and colors (60x95" Red pictured) with prices starting from $6.84. Opt for in-store pickup to avoid the $5.99 shipping charge. That's around $10 less than what you'd pay for these kind of curtains elsewhere (depending on size). They're available in 60x54", 60x63", 60x84", and 60x95" across select colors.
