If you’ve ever spent more than 5 seconds sorting through your mismatched food containers to find the right lid, it’s time to throw them all out and upgrade to the uber-popular Rubbermaid Easy Find Lid system.

These containers come in six different sizes, and yet you only have to deal with three different lids, making it much easier to find the right one. The 42 piece set is on sale for a $18 right now on Amazon, which isn’t an all-time low, but it’s about as cheap as it tends to get these days, outside of short-lived flash sales. If you already know you love them, or are dealing with a large family, the 60-piece set is also down to an all-time low $27 right now.
