The one thing I can tell you about plastics manufacturers is that none of them are interchangeable unless they meet an industry standard. This is partly due to competition and partly due to copyright protection. The concept of a sealable tub is not patent protected, but the individual footprint is governed by a proprietary mold protected under copyright law. This is a long way of pointing out the obvious: if anyone has tried to use a lid from one maker on another, and it fits, it would be a pure coincidence.
This is the reason why I purchased what hopefully will be my lifetime need in one buy. You can almost guarantee that once this mold wears out, the manufacture will discontinue the product and the new product will not be stackable on the old product. This is how plastics companies like Rubbermaid force consumers to throw out perfectly good tubs because of lost lids and lack of intermateability. It’s also why you rarely if ever see plastics companies offering their product as piece parts.
So the advice I would give anyone. Buy this product “NOW” if it suits your needs and buy a lifetime supply “NOW”. Because you won’t find a similar one at that size that isn’t part of a “collection” and it’s more than likely that as soon as the manufacturer’s mold has exceeded it’s life span, they will likely move on to the next product.
However, there was sufficient information in @Lexi link. If you look in the fine print, you will see the manufacturers SKU which in this case yields several online and brick and mortar vendors who sell the product.
