Actually, this is not very necessary. But if you don’t want to enter your address and contact information over and over again, you should become a member. It is also useful to see an inventory of your previous purchases from us. THE MOST IMPORTANT THING IS THIS: If you are a customer who has purchased products several times and you are a member, our system shows how many times you have purchased products from us next to your last purchase. We offer more flexibility to our regular customers, of course!
