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.
