According to the data on ebay feedback (so not greatly reliable) we will be about 20% higher on revenue on last qtr for ebay. The average value of each sale in the feedback is down $15 from June ($140) to July ($125). So although we are still getting good amount of feedback people appear to be spending less per item. The same value so far is tracking for August ($126).

value of ebay feedback
Jan-Mar = 181k
Apr-Jun = 582k
Jul-Sep = 705k (estimated 1 and half months in)

If we use the same 23% of ebay sales leave feedback (referred to in my and $tockfella post end of last qtr https://hotcopper.com.au/posts/54204032/single) then I predict Ebay will be around 3.05m revenue this qtr as we currently track which is an increase of $0.5m. $tockfella To reach your $14.4m prediction we will need all other revenue areas to have gains for the remaining 1.34m. Let's wait and see.
