Sold for a Purple Energy Cannonball + 10 keys pure

~ 120 keys

Sales at 150, 130, 105, 65, and 120. Taking 65 out as an outlier(since all other sales are above 100). Taking 120-150 as the range.

This is my first unusual suggestion. Big thanks to Polar for supplying the minis. Open to advice/feedback.
