Why aren't the prices shown? What currency do you use? I am a consumer and interested in purchasing your products. How do I place an order? Do you also deliver abroad? If so, are there any delivery charges? I am a wholesaler, retailer, or distributor and interested in becoming your partner. How do I become your     business partner? What are the payment terms? How long does it take for the products to be delivered to me? How do I know which size would fit my pet dog? Do you have a quick reference(breed) to know what size fits my dog? Do you have any larger sizes for bigger dogs? Do you allow to exchange after the product has been purchased?
