Hello UK customers! We are very sorry, but the new rules for shipping to the UK, as well as taxes/fees, have made it prohibitive for us to continue to ship there. We are very sorry for this, but perhaps things will change in the future that will make shipping to the UK a viable option.

Shipping for spray paint is only available in the contiguous US and must ship by ground. If it is purchased along with other items, the entire order will ship via ground. If you want your other items faster, please select a separate shipping option.

We ship via Priority USPS with tracking, UPS, and FedEx. For orders with a shipping weight of less than a pound, we offer USPS 1st Class Package shipping with tracking.

We send out USPS packages M-F, except for federal holidays when USPS doesn't ship. If we receive your order before noon (Pacific time) M-F (Thursdays ship at 9am), it will likely go out that day.

UPS and FedEx packages are sent out on Wednesday and Friday.

If an item is damaged or has been sent in error, we will pay for return shipping and replace the item if it is returned within 30 days purchase.

If you ordered the wrong item or changed your mind, you may return the item provided that it is in new condition and within 30 days of purchase. You will be refunded the purchase price minus a 10% restocking fee. The restocking fee does not apply to exchanges.
