Alright, I was mistaken...

I got this e-mail from Ali at Animal Plastics who was doing some background checking for me, and this is what they said:

I had someone call Sterilite today and they informed us that the 1752, 1754,
1756, and 1758 are not being discontinued, but will be made exclusively for
Target. They will not be found anywhere else, except for Target. So it looks
like we are good to go.
