eBay: 7-Day auction any more lucrative than 5?

[Grateful11]

[quote TL][quote Chupa Chupa]My M.O. is to set the auction for 3 days to get it closer to the top of the list. If there are no bids after 2 days I switch to a 5 day auction. At day 4 if there are no bids I go to a 7 day and let the clock run out. Can't do that anymore. You have 2 hours after listing to extend the duration, but that's it.
When did this start because I just extended one the other day?
