PLEASE USE EBAY’S SHOPPING CART SYSTEM FOR MULTIPLE PURCHASES. Whenever you are buying multiple items from me, simply click "Add to Cart" on each one. Then, when you are done, just click on the tiny shopping cart symbol in the upper right corner of the screen. That will show all of the items you want to buy and you can buy them all at once instead of one at a time. That is much easier for you (the buyer) and it saves me (the seller) from paying a separate PayPal transaction fee for each purchase. So, it's better for both of us. Thanks!
