This is definitely for those that are completely new to T-Shirt marketing. It comes with loads of ready made art work and ad graphics, but remember that it always better and more reliable to have your own graphics and ad style.
If you have never done T-Shirt marketing, this will provide you a glimpse into the opportunity, but it does not give you the more in depth and needed details of running great T-Shirt campaigns. For that information, I think you are better served by some of the other shares here on BBHF from the recent past.
If you are new to this, give it a good read and study the graphics, then have your own graphics created if you want to have a better chance of selling your shirts.
