its a strange thing... the whole "lights on/off" thing is in full effect i am positive

for example...2 recent events

i had 8 sales last Friday
then on the following 3 days (Sat/Sun/Mon) i had 2 sales

then on Wednesday evening just gone i had 6 sales in a 90 minute period
Thursday 2 sales and today 0 sales (so far)

i am convinced all the small sellers are on rotation.. maybe its where we appear on "best match" or at certain times our items are unsearchable.. i dont know.. but i do know it exists
