-plenty around 7.66ref - 8 ref

- quite a lot unsold ~1 key

1 key sales clearly doesnt happen enough on a regular basis for it to be included in the price. Not that difficult to find sellers around 7.66ref-8. Some sellers below 7.66ref but not enough of them to be included in the range atm.

Please tell me if ive made a mistake or if im missing anything
