Local Pickup FAQ's

What is Local Pickup?

Answer: This and many other products are now available for order online and pickup at the Power Equipment Direct warehouse in Bolingbrook, Illinois or at a Ferguson Supply location near you.

How Do I Update My Pickup Location?

Answer: The nearest pickup location within a 50-mile radius is automatically chosen when you enter the site. To change your pickup location and see availability for other nearby locations, click the "Change Pickup Location" link on the product page or in the cart.

How Do I Place a Local Pickup Order?

Answer: Eligible items will have the Local Pickup option available both on the product page and in the cart. Select this option for all items you wish to pick up. Please note that Local Pickup can only be scheduled online at this time.

When Can Items Be Picked Up?

Answer: Items are usually ready for pickup the same day the online order is placed, but this will depend on order volume and time of day. When your order is ready, you will receive an email including specific pickup instructions. Orders that have not been picked up within two business days may be cancelled. You should opt to have your items shipped if you are not able to pick them up promptly.

Who Can Pick Up My Order?

Answer: You will be prompted to enter the name, mobile phone, and email address of the person who will be picking up the order during checkout. We will use this information to ensure the order is picked up by an authorized individual.

Why Can't I Select Local Pickup for Some Items?

Answer: Not all items are available at all locations, so pickup availability will vary based on the selected store. Additionally, some items ship directly from our manufacturer partners and are not available for pickup. You can use the "Change Pickup Location" link to check for availability at nearby Local Pickup locations.

Why Can't I Select Shipping for Some Items?

Answer: Due to packaging, shipping costs, and other factors, some items cannot be shipped and are offered exclusively through Local Pickup.

Which Payment Methods Are Accepted?

Answer: Credit/debit cards, Apple Pay, Google Pay, PayPal, and financing are accepted for Local Pickup orders.
