During checkout on the shopping cart pop-up, there will be a field that reads "Apply a Coupon". At this time, there's no field to type in a code, but if you have coupons associated with your account (such as receiving them from newsletters or email), they will appear on the dropdown menu after clicking on the Apply a Coupon button. Choose the coupon you wish to apply and your order total will update.

Shipping is instantaneous, as purchasing this bundle of games is an online transaction. After purchasing your bundle, you can redeem the games included on Steam. Refunds are issued at the discretion of Humble Bundle within 60 days of purchase. However, games that have been played for multiple days are not eligible for refunds. Humble Bundle monthly subscriptions are also typically not eligible for refunds. If you have an issue with compatibility or downloading or have some other tech issue, you can contact their support team for assistance. There is also an order resender feature for added convenience. A monthly subscription can be canceled at any time by logging into your account, but to avoid being charged for the upcoming month, you should cancel within 7 days of the next Humble Bundle distribution date, according to your subscription.

Humble Bundle can only be contacted through their Support Page at this link - https://support.humblebundle.com/hc/en-us/requests/new. You can also reach out to them on social media on their Facebook, Twitter, and Google+ pages.
