My initial order was erroneously placed for the same pet pen, but without the door.  When I realized my mistake I phoned Wayfair & was assisted with courtesy & a quick response to replace it with one w/ a door.  I did have to drop it off at a UPS facility, but only encountered a small fee for shipping in both directions.  It was a fair price to pay for my mistake & the puppy & I are very happy to use the pen.  It is easily moved & easy to set up.  It fits in my car trunk, but is a little difficult for 1 person to carry alone when in the folded position.
