Sam's Club offers its members the Rubbermaid Easy Find Lids 36-Piece Set for $9.98 with free shipping. (Non-members pay $1 more.) That's a very low price for such a set. (For further comparison, we saw a similar 20-piece set for $7 via in-store pickup four days ago.) Sales tax is added where applicable. The lids and bases in this set nest together. Deal ends December 2.
