Thanks to the help of a couple folks here, I was able to enhance the graphics on some of the shirts, and bring the price down a bit. I also added a few new ones.
Here's the inventory so far, in case anyone is itching to buy one:
The new "Basic Tee":

This shirt comes in ash-gray, and black, as well. This is the biggest breakthrough, in price. you can get one for under $10 now.
The "Quotable" and the original "Red Pill" shirt remain the same:

There's now a new gray "Jerzee" brand Tee, with the new graphics:
There's now a version of the "Red Pill" shirt, in black:


There also now a tee with the logo on the left breast (suggested by MAF!):

A basic white polo shirt:

A fancy blue "Jerzee" brand polo:

Your standard gray hoodie:

Now, a new BLACK hoodie, with the new graphics:

Also, a new gray hoodie, with the "Red Pill" slogan on the back:

And, finally, some hats:
The "BDU" cap:

The standard ball cap (available in blue or black):

If anyone has any further suggestions, I'm open to them...
