Well the highet bidder will win, reguardless of how they snipe. So the #1 thing to remember is the high bid wins. Sniping is just an extra little tool.
The seller probably recommended us because we're the best. We have many feautres, are easy to use, are very reliable.
One time you can use is to enter your bid in a odd amount. Such as 5.03 rather than 5.00. Everyone bids in even dollars. So sometimes that extra 3 cents will sneak in the win for you.
In the case of a car I'd be 7503.53 instead of 7500 for instance.
