At least that was the case in 2018. They could have moved, or shrunk, or could be different facilities (not likely, imo).
Or possibly, when privatelabelpartners.net and privatelabelpartners.com "split" apart into two facilities, it could have changed the square footage?
All guessing as to why the disparity of Square footage...but I'm not worried about it. The company might answer that question in an email.
