I don't want to come off as someone who's never pleased and I appreciate that you are willing to make a vote now, but what you're doing now still isn't the best. For one, anyone can vote on this poll regardless of whether or not they have an order. For two, the vote should be focused solely on one thing, does the person want his chips or not, and once you know who wants to keep chips, you can ask them what they want to do with them.
I strongly recommend doing exactly what the other two group buys have been doing: send a PM to everyone involved asking them how many chips they want to keep and where to send the refund if applicable, then count the replies. I know this is more time consuming for you, but it's pretty much the only way of getting accurate results, you'll know exactly how many chips are wanted, as opposed to this poll, where someone with 1000 chips matters as much as someone with 16.
