Welcome to the Potomac Supplies on-line Philatelic Accessories Store. We hope that you will find the items that you need. We offer supplies from most major philatelic manufacturers. You can find just about anything you need for stamp collecting in one place. As you navigate our site, you will find that we have quite a variety of products for sale. We use retail pricing as listed by the actual manufacturers price list. You will NOT be asked to join a club to receive a discount either. We offer discounts for ALL the brands we carry. However, not all items are discounted nor are all items in stock. Some are ordered as needed from the manufacturer.
It is our policy to not give away any of our customer information to anyone. This includes any of the limited information about you, including your email address.
Thank You, for choosing Potomac for your stamp supply needs.
