I am posting this in DIY, too, so sorry if you see this twice!
Got my VISTAPRINT STDs!! I'm already sorta wanting to do a different design because I feel like I've been looking at these for so long! lol They turned out great- print quality on both the magnets and the postcards are awesome. I would suggest not doing a design that really requires it to be perfectly centered, though. Most of the postcards were printed SLIGHTLY too low and slightly off-centered. Might have been my fault, but I used their templates. Overall, I'm very happy with it!
I realize I have a ticker, yet I blurred the date. I just don't want to make it too super easy for someone to stalk me. lol
