Why do some Safavieh rugs arrive with creases or thin spots?

It's a documented complaint. On r/homeowners, owners report Safavieh rugs shipping folded with creases that won't relax and occasional uneven hemming, while others on r/femalelivingspace and r/BuyItForLife say theirs held up well for years. The consensus is that quality is good for the price but inconsistent unit to unit, so inspect on arrival.
