The listing, Tiered Mystery Office Supplies has ended.
Could be greeting cards, stationary, designer pens/pencils, fun erasers, markers, just about anything, really. All new. Value will depend on final bid, based on the day's exchange rate, plus a bonus. (so if it were ending now, the exchange rate is 12,100 credits=$1. Say bids go to 60,000. Based on the exchange rate, the value would be $5 but you would probably get $10 worth of stuff.)
