JKAdam,
Even if you have to use separate tiers for different levels of cards, there is no reason to package separately or pay extra shipping.
I recently sent sgc a package with two crossovers and one card for grading. I filled out a separate invoice sheet for the two submissions (ie one submission was the crossovers, the other was the card being graded raw). Made sure that the proper invoice was rubberbanded around the proper card or cards (after putting the raw card between a sufficient amount of cardboard to protect it during shipping) and sent in one box with instructions that should one submission be completed early, it be held until both can be shipped together. I also usually only fill out payment information for shipping on one of the invoices if Im submitting from multiple tiers and make sure to reference it on the other invoice(s). Never been a problem for me.
