How much does shipping cost?

How long does delivery take?

Please allow 5–7 business days for packing and dispatch. Carrier transit time is in addition to this. Express shipping speeds up carrier transit, not packing and dispatch. You'll receive tracking by email when your order ships.

Why did my order arrive in more than one package?

Some partner-brand items ship separately from their own location. Their shipping charges and delivery timing can differ, and are shown at checkout.

Can I return a product?

Yes. You can return unopened, unused items in their original packaging within 30 days of delivery. The buyer pays return shipping unless the item arrived damaged or we sent the wrong item. Approved refunds go back to your original payment method after we inspect the return. Please email us before sending a return, because partner-brand items may need to go back to a different address.

What if my item arrives damaged or wrong?

Email us within 7 days of delivery with your order number and photos of the item and packaging. We'll replace or refund it.

How do I use Hull Renew safely?

Hull Renew is a hull-cleaning powder containing oxalic acid. Always follow the directions on the product label for dilution, application, contact time and rinsing, and use it only on the surfaces the label lists. Wear gloves and eye protection, rinse treated surfaces thoroughly, and keep the product away from children and pets. For handling and storage information, see the safety data sheet.
