I buy almost all of my certified autographs from COMC and usually get them shipped between 20-70 cards at a time. Because they're mostly cheap cards, I just get the basic shipping with nothing added. Although the standard shipping can be slow, I've been nothing but pleased with their packaging. As another member mentioned, they'll included a couple toploaders for the end cards and all others will be in penny sleeves. Even with the basic option you won't have to worry about them getting damaged en route (well unless you use Canada Post, but that's a whole other thing...)
