COMMON QUESTIONS

Where's My Order's Tracking Link?
Tracking info is shared via email within 72 hours of most orders being placed. Be sure to check spam or "Promotions" folder in your Inbox, as sometimes our messages land there.
No Tracking Info Displays on Shipper's Website ...
It can take 48 hours for tracking info to display. Rest assured, your package is en route. Make sure to enter the BOL # (Bill of Lading) with no spaces in the tracking field.

Alaska, Hawaii, Puerto Rico?
Yes, we have shipped to these locations for decades by quote. Please share your address, the item(s) you needed shipped, and if an airport cargo depot pickup is possible.
Canada and International Locations?
We ship to Canada lots, and the Caribbean some. Get a quote. We rarely ship items to Europe, Asia, and Australia as it's spendy. Quotes for international orders do not include import duties.

How Can I Be Sure My Board Arrives Intact?
Opt for our $99 "To Nearby Airport" shipping option at checkout. It relies on passenger planes, and offers our safest delivery. More far below.
What if My Board Arrives Damaged?
We'll work with our shipping partner to get you a repair credit or a replacement board. Please send photos of the damaged board (and box) to shipping@bigwinds.com.

My board made it ...
But no foot straps, fins, or vent plug?
Look closely through the packaging. Fins, foot straps and vent plugs are often concealed in a sheath of cardboard that's easy to discard. Also, check inside the board box, and shake the box to be sure. You'll likely dislodge a small box containing the missing items.
