Kickstarter only allows 1 reward level per backer, so if there is something you would like to get in addition to the reward you have selected, you can include Add-Ons. These are popular items that many backers have requested. To get an add on, simply increase the actual dollar amount of you pledge level by the value of the Add-On. At the end of the program, you'll be able to specify the particular Add-Ons you want. There is no extra charge for shipping Add-Ons unless stated next to the price.
Note: miniature Add-Ons are not available with the Warrior Reward level, as it is shipped in a flat-rate envelope and additional items are restricted by the post.
