I haven’t gone into any of my local Dept store “supersales” (usually 9-1 pm Sats) in YEARS because the lines to the registers have two dozen or more people in them at all times, more from 12 noon to 1 pm) and the stores are a wreck where you can’t find anything. WHY? One has to only take a look at the parking lot for the answer to this question.
This “border-crossing shopping group” has a LOT MORE discretionary income (cash sales, NOT credit) than their co-workers, who live in the US. Why?? Their cost of living is so much lower. It’s not uncommon to see several customers at once during these “supersales” with a dozen boxes of shoes sitting on top of one another on the floor next to them in line at the register at Macys … taller than they are.
