To the new guy on here defending his business, I'll say this:
Not only did you potentially lose customers, but also potential future customers. I've never shopped with you before, and now I don't plan on it. On the flip-side - had you of honored Ryan's request in the first place, I would have seen that as great customer service and would have become a regular customer.
That's how I've picked all of the retailers I purchase online from - is their customer service.
I had never heard of Third Eye Comics before, but someone here posted an experience they had with them and how wonderful they were to deal with, they're now my go-to comic retailer.
Same with a mom and pops computer part retailer.
You could have made many new customers that day had you owned up provided Ryan with good customer service.
Lastly, as someone who works with web servers everyday, I don't get the whole "server issue" thing anyway. You need to update a price, you update it. It doesn't have to travel through multiple end-points or anything. Either your site is down or its up, its one database feeding the information. If one portion wasn't working, none of it would have been.
Anyway, regardless of the handful of people here who may no longer shop with you, I'm sure you'll be fine in the end. Don't let this get to you too much. Just try to do the right thing next time you find yourself in a similar situation.
