I think that the time some of these carded figures can't be posted will soon be upon us. If not already here.
I bought a really nice Lumat all be it with a yellow bubble, from a well trusted guy last week, only to receive it with a nasty crack and hole in the top of the bubble where his ear had come through during posting.
I will certainly think twice about posting yellow bubbles and will keep my MOC in GW acrylic cases rather yhan risk posting them for grading.
I see a graded figure as that was the grade when it was graded, it might not be like that now or in the future.
