I learned (the hard way) that since you are charged individually for shipping anyway, you are better off ordering individually. I've only ordered from them once, but had 3 items in the order. I had a problem and had to cancel BUT:
-newegg had "already shipped" (actually, the order was in different boxes, one of which was packed and in THEIR shipping shed (...for another 12 hours before the carrier picked it up)) and therefore "couldn't change anything".
-the other parts were still sitting cozily on their respective newegg shelves. But since they were "in the same order" , "no changes could be made". (read 15% re-stocking fee...) and those parts were also doomed to be eventually woken up, dusted off, and packed in a box for a trip ending up back at newegg before they could be restored to their snooze.
Had I ordered separately, the shippingwould have been exactly the same, but the restocking fee would only have applied to the first "already shipped" item. (I do have trouble accepting that label for an item that continued to sit on their dock for another 12 hours before the shipping agent ever saw it) Therefore, since they are going to charge you the same either way, you're better off making each item an individual order to give yourself that much more flexibility if something comes up!
