+1 on the poor choice for printing. It's a shame, this is a great design, but as my wife said when I put it on this morning "all I can see is a white blob".
This isn't the first woot shirt I've bought that was very difficult to see because the shirt color didn't go well with the artwork, but it is by far the worst.
I love my woot shirts (my wife hates it when that bag shows up in the mail), but this will definitely make me second guess future purchases.
Here's the thing, I'm not upset about the cost, but more that the design isn't as good as it could be. I would pay $10 again for the design printed on a different shirt color.
