I just have a log-in with Ed's site and you can place stuff in your cart and continue to add to it and check out at a later time when he is processing orders. Very handy when you want to build up an order. I have had my cart sit for several weeks until I get the order built that I need. This works great. Ed places really well printed out labels on all his plastic packaging that has the Molex numbers on them along with the name of the item. That makes it easy to ID the specific part in your kit when you start to do your work.
