Yikes! Sorry you had to go through that!! I can't imagine how frustrating that must be. Especially after taking so much time to do that. :/
As a wedding stationery designer, I'm really nervous about using Vistaprint for myself. I've heard horror stories from fellow designers about streaking, poor color, poor paper experiences, etc with VP. I also think they have odd trim sizes. BUT.. the deal is so amazing that I'm going to take a chance with it for some of my OOT bag stuff. Crossing my fingers!!
