Do you ship the same day?
Dispatch is normally the same or next business day, and heavy items travel on freight with a booked delivery window.
What happens if it arrives damaged?
Report any transit damage with a photo and we will send a replacement or refund you. We handle the carrier claim ourselves.
Is this checked before shipping?
