Check out my other listings as I do combine shipping. My settings will automatically correct the pricing in your cart as you add items. If you do purchase more than one item with combined shipping (particularly if one of them has a flat rate shipping price or if the different listings have different speeds of shipping, I may use a different shipping carrier (including USPS, UPS, or FEDEX) or change the shipping speed to keep costs reasonable).
If you see markers in the pictures, they are a reference to color and not pointing anything out. :-)
