Summary

Sales at 9, 10, 10, 10, 10, 11, 12, and 14.

Marketplace sales are at 7.5, 8.5, 11, 13, 13, 13, 13, 13, 14, 14, 14, 14, 14, and 18.

Conclusion

Going to exclude 7.5, 8.5, and 9 due to current buyers.

Going to exclude 18 due to multiple sellers at 13/14 during the time.

There are buyers at 10, however, there's a total of 6 sales at 10, which makes it common here.

Going to go with 10-14 here.
