I haven't seen chargers going for 9 mill yet. Everywhere I seem to shop it's 6-6.5, but then again I only shop at cheap vendor malls, then resell at luna, haha. However, I don't sell any of my chargers that I have for more than 7, so I dunno. The ones at 9+ might be older vendors from the pre-dupe bannings that just never changed their prices.

edit: there are actually two chargers for 6.5 in Luna right now at the watchers shop, with all the golden robes. That is a fair price if you're looking for chargers Ally.
