And with Pictureframes you have the choice of paper.  I think a sampling is around $5.   When you upload, you can order as little as 5 at a time and they send you a proof that you have to sign and send back before they'll begin printing your giclee order.  They include authenticity sheets that you fill in with the print name and if it's an open edition, etc. 

The only issue I've had with them is the fact that I use a Po Box and their "standard shipping" is ups.  I always understood "standard shipping" to be USPS but they weren't very descriptive.  The first proof was either sent out and returned or never sent but once they learned why they sent out another to my business address with no problem.
