davidcyclebackAs noted, you have to be a brick and mortar store to get the cases directly from the manufacturers-- and they wouldn't allow you to break up the cases on eBay.  I would think it might be tough to resell the cards for profit on eBay anyway, so I don't think you're missing out.  Plus new stuff tend to drop off a cliff price wise when the next year's stuff.
There are wholesalers you can try to get cases from, if you want to try the avenue.
