For what it's worth, here is what I would do.
Announce the sale with a deadline date, price list, and percentage limitations on quantities. Up until the deadline, accept orders by email with total quantity of chips ordered listed in the message title. After the deadline go through the orders beginning with the highest quantities first and do a trial allocation on each order until running out of chips (rejecting invalid orders along the way). After the available chips have been allocated to the orders, make an assessment as to whether the results represent a fair and reasonable distribution of chips. If the distribution doesn't pass the assessment, make adjustments using whatever privately determined criteria seems best. Send out invoices.
