Shouldn’t this update at the end of every week at the very least? I haven’t payed much attention to it before.
Is it updated at the (calendaristic) end of each month? Seems like the sales volume for the past 90 days would be more accurate.
Twicet for instance has almost 1000 purchases now.
If you’re talking about the Weekly Top Sellers, they do get updated every week, but the sales count is the sales count of that week (in this case, the most recent week is Monday 5th of october until Sunday the 11th)
If you’re talking about the last three months though, you can see the same thing happens, it shows the sales up to a certain date (in this case 30 September).
If you’re talking about the top authors, they get updated each month with the amount of sales they make.
