Shipping fees are based primarily on size, not on weight. I can ship a hat and a t-shirt for the same cost as a hat alone as the shirt will fit in the same box. If you add multiple items to your cart you will be automatically discounted the excess shipping fees. As another incentive, if you buy one item you will get the 3”x3” logo sticker free, and if you buy 2 or more items you will get the 9”x4” bumper sticker for free. These items will be added to your package when shipped.
