LightBulbs.com Shipping Policy:

We do our best to provide very affordable shipping rates and to get your order shipped out to you as soon as possible!

Rates

Our flat rate for ground shipping to the 48 contiguous states is $10.99. Surcharges may apply for larger orders. For shipments to Canada, you can add some items to your cart to determine the shipping rate.

Certain longer fluorescent/LED tubes and 4' ceiling fixtures will be assessed a shipping surcharge; this is to cover all of the additional shipping materials that are needed to ensure a safe arrival.

Carriers Used

We use the United States Post Office and FedEx for our shipments. The exact carrier and service used is calculated once the order is packaged for shipment. If you require a particular shipping service for your address, additional surcharges may apply. We never guarantee a certain method for any order unless it is an express order.

Most in-stock orders will ship out within 24 hours and will reach customers within approximately a week. For express delivery methods, every effort is made to ensure those in-stock orders are shipped the same day, provided the order was received by 1PM Central Time. In some cases, the order may ship the next business day.

Orders are shipped from Minnesota, ensuring a reasonable shipping time frame to both coasts as well as the areas in-between.

We email tracking numbers to customers once orders have shipped, provided a valid email address is on file.

Issues with Shipping

If a shipment is missing, our Customer Service team needs to be notified within 7 days of the carrier acknowledgement of delivery so a timely claim can be filed.

For shipments outside of the USA, we are not responsible for damaged or missing products.

If a package is confirmed by carrier to be delivered to the address provided by the customer, and the package is reported as missing, the responsibility falls to the customer to file a missing package or theft claim with the carrier used.

Much of our shipping process is automated - there are times when orders will ship so quickly that cancellation requests over email/phone will not arrive in time. In these instances, the shipment will go out and our return policy will apply.

We are open! Our response to Coronavirus (COVID-19)
