I guess it was on sale because the moveable shoulder pad is upside on the strap, or rather the strap was sewn onto the bag upside down.  There's now way to fix this without twisting the strap, or removing one of the sewn ends, or removing the shoulder pad and re-sewing.

Too bad the strap isn't removeable.

Other than that, which I consider minor enough not to return, the bag meets all my needs with zipper closings which is VERY important to keep things from slipping out.
