The listing, Tiered My Coke Rewards points has ended.
15-25 credits - 9 points
26-40 credits - 16 points
41-50 credits - 20 points
50-60 credits - 30 points
61+ credits - 42 points
Every ten credits after 61 (71, 81, 91, etc.) adds three more points. These values are based on other auctions I've listed and observed, so if they seem a little weird that's why.
Normally I don't like tiered auctions, but they seem to work pretty well and people seem to enjoy them, so we'll get it a try. This is largely an experiment, and if it works out I'll probably do more of these in the future. All codes will be emailed to winner at auction's end. Thank you!
