Nice job. You seem very professional, and open and available to communicate to answer questions and provide assistance. Good customer service is unbeatable in my opinion, and makes me want to return to a vendor again for repeat business just to support the awesome people running the business.

Here would be my suggestions:

1. Keep your business operating withing scope, so you don't get burned out or cranky with customers. Keep them number 1, like you are right now. That will take you far! Read encouraging comments (like this one!) to remind you that the customers are not all beasts.

2. I agree with other comments that top games/deals should be highlighted with a small blurb about the game, or show how much discount it is. Even though I see a cool banner showing Borderlands shown on top, I don't know what kind of game that is, or why I might like it. Some context on the featured game would help.

3. I am unfamiliar with how games are purchased sold in this style. The text about how you need to chat with the buyer on Steam is clear, and helpful. Are these games you have downloaded and played on Steam, and are able to sell? I'm not sure how that works. Is there a code/key that is given that disables your install, and allows the buyer to install and play from Steam? As a first time buyer, it would be helpful to have answers to questions about purchasing from you. Maybe you could link to a vendor page, to answer common questions, and also show the positive feedback from buyers, to give you more credibility.

This looks like a good service. I would love to see more store-fronts revised weekly/monthly here on Steemit for people to browse and shop from.
