Ebay Tip

If you happen to want something that has an identical listing (or more) at a different time no more than 12 hours apart, go for the earlier listing.

Rationale:
1) bidders who have failed in bidding the earlier listing would bid on later ones.
2) bidders take the earlier listing's final price as a benchmark, hence bidding around that price (more or less, but probably more, to secure this later listing).

Forgetting to bid on an item that ended at 8PM (finalized at $32), I knew it was gonna be a bad idea if I'd bid on the 9:30PM listing. I did, nonetheless, and got it for $61.
