Shipping & Returns
Shipping:
Most qualifying in-stock orders are processed within one business day. In the contiguous 48 states, eligible in-stock orders placed before 12:00 PM (noon) in the customer's local time zone typically ship the same business day. Orders shipping to Alaska or Hawaii use a 12:00 PM Pacific Time cutoff (California time). These cutoffs apply only to eligible in-stock orders and are not guaranteed shipping or delivery times. Same-day shipping refers to processing and carrier handoff, not delivery. Weekends and holidays are excluded.
Payment verification, address verification, fraud review, and inventory availability may take longer. Supplier-direct fulfillment, freight shipping, and special handling may also take longer.
Returns:
Eligible products may be returned within 60 days of delivery, subject to our Return Policy. Return authorization is required. Certain products are final sale or subject to manufacturer warranty procedures, shipping charges, and applicable restocking fees.
Please inspect your order promptly upon delivery. Shipping damage, incorrect items, missing components, or quantity shortages must be reported within 3 business days after delivery. Retain the product, original packaging, shipping labels, and photographs while your claim is reviewed.
