美国采购需求：新款棉拖鞋，女士冬季棉拖鞋

I hope this message finds you well. I'm interested in purchasing a pair of your shoes in the stylish white color. Specifically, I wear a size US Women's 7. Could you please provide me with the pricing details for this size? Additionally, I'd love to know about any bulk order discounts or special promotions you might be running right now. Also, if you could share information about the estimated delivery time and shipping options available, that would be great! I'm eager to consider a potential order, so any further details regarding the product, such as its availability and materials used, would be very helpful. Looking forward to your prompt response!
