i dident know where to put this as you only have a CARD shop and not a GFx so i will just put it here for now:
sigs will cost 300 gx points
avatars will cost 150 gx points
if you want banners for a diffrent acad that will cost 500 gx points
anyother gfx you need just post and i will give a price
here are some gfx i have already made(NOTE: these ones are for display only)
