Right now, I have paid for the Baseball Forecaster from Baseball HQ and Baseball Prospectus 2011(yet to be delivered). I am still deciding if getting Baseball America Prospect Handbook a couple weeks early is worth overpaying to order through BA.
The money isn't the issue as I have enough. Nor is the chance I'll be disappointed in the product. I just loathe paying 7-10 dollars for shipping when I know the USPO charges more an half as much.
