Yes, you can. All shipping will be collected after the KS so if you and several friends want to join together to lower that cost you can. Every simply pledges at the level they want and then after the KS let us the Address and who all will have they're pledged shipped there. This will result in one backer being charged the joint shipping fee. Why do this? The base shipping rate will only go up by a small amount and you can then split it save money.
We have been asked this a few times, in short, if you want to purchase more then one Steel Level Pledge please contact us. Kickstarter doesn't make this an easy process but we have something in place to help out.
We will allow for late pledges both here and on Indigogo but be aware that prices will go up for late pledges. The only way to obtain the games and play mat at the current price is if you pledge during the KS. Even a $1.00 pledge will get you access to these prices.
