Easy return policies, better online measuring instructions are your answers. I’m going to guess you’re an older couple - most people in the prime 18-34 demographic are no longer seen at malls. All demographic ages are appearing in malls and in brick and mortar stores less.
Even physical stores in low rent situations are struggling. The drop in profitability is not linked to rents.
Hmmm... well I do fall outside the prime demographic you note, but my kids still do shop at the mall and seem to enjoy the mall experience. They are on the low end of the prime demographic, but the mall in our area is still pretty vibrant, although you wouldn’t catch me there — ever.
