If you list for a single day, obviously your at the top of the list and most likely to get the attention of those who only bid at the last minute.
The fact you can automatically renew for three consequtive times means this is effectively a three day auction.
Of course, if the item didn't sell, you'd have to relist again on the fourth day under a new auction number.
If you're a bit more lazy, then choose a 7 day auction format with triple relists for a 21 day run.
If you like the idea of once-a-month relisting, then just list for ten days with three relists and you won't have to relist but once a month.
If you're really lazy and have a lot of product and have a good price on it and just want to sell it, list your items in a multiple item For Sale listing with a 30-day run and three automatic relists.
Require bidsafe and sit back and ship the item when you get confirmations.
