The saving from using this company was not worth the hassle. They use UPS. Arguably the worst delivery company out there. Very expensive and totally inefficient.
Edit: Following nonsense reply from seller.
The “extreme weather” was snow on Friday 10/3. The parcel was due Monday 13/3. It did not arrive. No updates were received. The UPS page was not working so no information regarding this could be accessed. The whole day was wasted waiting in. The delivery occurred a day late. Again no notifications were available as the UPS page could not be updated. It was luck that someone was in to take delivery. The very courteous delivery driver informed us that the snow occurred on Friday. He acknowledged that UPS were hopeless at keeping customers informed with accurate facts and that it took three days for UPS to get organised following the Friday disruption.
