3D Files

[Dickey Beckham]

I am working on a small job and would like to make the photo look better, so i added so 3d files
that i downloaded from this site, IT seems that the more I add the higher the price goes up I
did not give it a cost when I save them in the HSF's directory, but evertime I check the selling price it changes
is it the 3d file that is making this happen and can I fix this. I have allso notice that the price will jump around
just by clicking on selling price with out any 3d file in it. can someone tell me what is going on. Thanks
