Check the listing for details. (1) HARRIS MI-6515-5 STATIC RAM NOS. Condition: New. Listed at 4.00 USD. (1) HARRIS MI-6515-5 STATIC RAM NOS Combined Shipping:With this listing and many others, the shipping cost should not increase no matter how many you buy of a given listing item. However, if you buy from multiple listings ebay may charge you shipping on each listing. The best way to avoid this is to use ebay’s cart system and request a total once you have all you want in it. I will then send an invoice with the shipping adjusted per your items. Or, that’s how it’s supposed to work, but it doesn’t always. There is also the matter of using a mobile phone app to buy, it doesn’t have the option to request a total, it needs to be from a PC. If all the above fails, simply pay the amount ebay demands and we will refund the overpayment when we ship, we have to do this every day, unfortunately. My feedback speaks for itself, I don’t cheat people on shipping cost.Thank You,Steve
