I'm looking to purchase a white smartphone that is known for its sleek design and excellent camera quality. My primary interest is in understanding the specifications, available features, and any bulk order discounts you might offer. Could you provide details on the pricing, minimum order quantities, and expected lead time? Additionally, if there are any special promotions or warranty options, I would love to hear about those. Thank you!
