I purchased this unit in May 2020. I love it. I use it to store undergarments and t-shirts. This means I'm in it daily and often several times a day. For the last 2 years, I've been trying to locate more of these and I've had no luck! Are you all no longer producing this unit? I have several Sterlite containers in my home and this has been the best one so far. When will more become available?!
