When will it arrive?
Orders placed before 2:00 pm ET on a business day ship the same day from Orlando; Saturday orders before 1:00 pm ET go out that afternoon. After that, it ships the next business day.
Delivery takes 3–5 business days after dispatch to most US addresses, and 5–8 to Alaska, Hawaii and US territories.
Can I return it?
Yes — tell us within 30 days of delivery and send it back unused, in its packaging, for a full refund. If it is faulty, damaged in transit or not as described, we pay the return; if you have changed your mind, the return shipping is yours, and we quote it before anything is booked.
Do I need to be in for the delivery?
Orders over $150 ship with signature on delivery, so a missing parcel can be claimed. Your tracking number is emailed the moment the label prints.
