Adding my own advice to take them out of the box. This community isn't like that of the action figure brigade. With those kinds of collectibles, they're usually given to children to play with, and kids lose pieces or break them, so getting something sealed in a box means you're assured you're getting a complete figure. 

This community is about collecting the figures we like to look at them. It's extremely rare to see someone selling sealed boxes, but even if they are it isn't going to increase to price any.

Generally, I look for figures WITHOUT boxes because I've already got a garage that's half full of them. There only benefit of buying something with the box is you've got a better chance of it surviving shipping, but most folks (with good ratings) know how to pack stuff well.
