Basically

I'm asking which mones you guys think are the best value and can last the longest.

From my experience a

bottle of NPA lasts quite a long time due to the small application amounts. I've had my NPA for almost a year now

and I still haven't finished using it. SoE roll-on seems to last quite a bit too with months of application.

Chikara and The Edge both seem to run out in almost no time, particularly Chikara. I'd say a bottle of Chikara

would go out in about 4 weeks of repeated usage, TE possibly longer.
