We will randomly select an order every month to include a free Grim Threads T-Shirt at no extra cost. The T-Shirt will be the same size as the shirt in your order. If more than one size is ordered, we will make an attempt to reach out to you in regards to what size shirt you would like. If we are unable to reach you, we will select the shirt size. The giveaway is for the Grim Threads shirt only. Because this is at no extra cost, there will be no refunds or exchanges on this free T-shirt. Good luck!
