how long does it take for flat rate shipping

how long does it take for flat rate shipping depends on the service used and the destination of the shipment. USPS flat rate shipping is known for its predictable delivery times, which are often faster than regular shipping methods. For domestic shipments within the U.S., USPS offers Priority Mail Flat Rate, which typically delivers within 1-3 business days depending on the destination. International flat rate shipping can take longer, usually between 6-10 business days. Using flat rate shipping is an efficient way for e-commerce businesses to save on shipping costs while ensuring timely delivery of products. By partnering with fulfillment services like AMZFulfill, businesses can take advantage of flat rate shipping options and improve their shipping speed and efficiency.
