Walmart offers two Better Homes & Gardens 1-Piece QuickFit Outdoor Outlet Covers for $3.96. (You must order a minimum of two.) Opt for in-store pickup to avoid the $5.99 shipping charge. That's $9 under the best shipped price we could find for the quantity elsewhere, and at $1.98 per item, it's also an extremely low price for an outdoor outlet cover in general. Each weatherproof cover features an opening in the bottom for cords to fit through.
