oh boy uhh

four dates out of date, but july 29 MP sale

$137.5 / $1.93 = 71.24 keys

this item is on more of an upward trend than it is a downward trend

(and if i happened to get to this suggestion on the day of the oct 23 sale, that july sale would've been in date)

54 sold for 47, 47 sold same day and in items of course

going back in time and going with 71-91?
