Hi Kerra,
 
So sorry to hear what happened with your cards, but I have no doubt that Shaun and other good folks at GCU will do their best to help remedy the problems.  I have tough time with borders, so I try to avoid them as much as possible ... but otherwise, I have been happily impressed with GCU's print quality.  My own cards come out exactly as specked both in terms of color and type.  I've also purchased cards from many other artists here and they all look terrific.  Obviously, I don't know if they look exactly as the artist thought they should, but I've seen no problems in the cards I've purchased.  As far as the colors go, I agree with the others about checking your monitor calibration and printing out a test before rendering a final version.
 
I believe GCU still offers one free sample card to artists when they join.  For anyone new to this, it's a very good idea to order a sample of one or two of your cards before creating a large inventory.  
 
Kerra, I hope it will just be matter of some minor adjustments that won't take too much time.  Your cards are adorable, so keep us posted on how things work out.
