I would like valve to:

Give Publishers the option to allow returns.

to allow returns. Give Publishers the ability to set how long a return is allowed.

Advertise for whether a return is allowed and for how long a return is allowed next to the price (similar to how steamplay is advertised).

This is in Valve's best interest as it cuts down on costs of customer service while increasing sales as customers less hesitant to buy a new product (if it has returns). Valve would not lose bussiness from publishers, but rather give its publishers another option to increase customer loyalty. This is also in the confident indie developers' best interest as it allows them the ability to get noticed and increase sales from people who were hestitant at first. I hope Valve understands this is an important step into ensuring digital distribution's future success.
