    Shipping / Cancellations / Returns

    Order Confirmation

    As soon as you place the order, an order confirmation will be emailed to you. This means we have received your order and payment. Payment is captured as soon as the order is placed. In rare cases, if the product is on backorder or unavailable, we will contact you and ask if you would like to wait for the product to become available, switch your product, or have your payment refunded. If the item is available for immediate shipment (1-3 business days) we will submit the order for processing and arrange shipment.

    Order Shipment

    Most products ship within 1 to 3 business days from the date of your order (unless indicated on the product page). Some items take a bit longer to ship since they are built to order (i.e., Timber Grow Lights, ChilLED Tech, Trimmers, etc). We will send you tracking information as soon as it is available. 

    U.S. Shipping

    We are based in Portland, Oregon with warehouses nationwide. We offer FREE shipping in the lower 48 states (sometimes to HI and AK, too) via FedEx, UPS, USPS or other major couriers (product/brand dependent). Expedited shipping is usually available for an extra cost. Contact us before your purchase if you prefer an expedited shipping method and we will get you a quote.

    After the order is processed, allow 2 to 7 business days for the product(s) to reach you if shipped to a U.S. address. We can ship to PO boxes in some cases. We recommend using a street/residential address instead.

    International Orders

    Nearly all of our brands can be shipped internationally using FedEx, UPS, USPS, DHL or other couriers. Most quotes can be obtained at checkout.

We charge a 2.15% (credit card / ViaBill), 2.6% (PayPal), 6% (Sezzle) order cancellation fee once the order has been processed (before it has been shipped). We can accommodate most requests, but due to the different time zones and schedules that our warehouses ship from, the cancellation request may not reach the warehouse in time. Once the item has been arranged to ship or has shipped, the package will be treated like a 'return' and is subject to ship-back fees and restocking fees. All EZTrim orders are final and non-refundable or returnable.


    We offer return shipping in the USA if you are not 100% satisfied for any reason. Many brands have a 90-day return policy. See our full Return Policy for rules and guidance on returning an item after purchase and for brand-specific return dates. A 5-25% restocking fee (brand dependent) may apply for returns within the dates of the return policy. Reach out to us for exact return instructions and restocking fees for the item(s) that you purchased.
