It's covered in the application booklet and I did a C/P of it here for you. Go into your account on July 20th when they go on sale and put in the unit you want and the number of tags you want to purchase. It will not allow you to buy more than what is legal in a unit or more than a total of four for all areas, so it's pretty much foolprooof the way F&G has it set up.
Here is the applicable section:
The Commission may authorize a sportsperson to possess more
than two (2) Reduced Price Doe/Fawn Deer or Reduced Price Doe/Fawn
Antelope licenses in certain Deer and Antelope hunt areas. The actual total
number of Reduced Price Doe/Fawn licenses a person can possess will
be determined in late April 2011. Regardless of the number of Reduced
Price Doe/Fawn Deer or Reduced Price Antelope licenses any person can
possess, a maximum of only two (2) Reduced Price licenses can be applied
for in the initial draw. If a sportsperson wants to purchase Reduced Price
Doe/Fawn Deer or Antelope licenses after the initial draw including up
to the maximum number allowed, they will be able to do so at automated
License Selling Agents or by using the WGFD website.
