so i am currently the highest bidder on something that i really want on ebay, but there are several others that bid on the same item. and the auction ends today, and i have never really bid on anything before, so basically, i am just wondering if i should expect the other bidders to outbid me or not. SHOULD I MAKE AN EVEN HIGHER BID IN THE LAST FEW SECONDS/ MINUTES? SHOULD I EXPECT THE OTHER BIDDERS TO OUTBID ME IN THE LAST FEW MINUTES OR SECONDS? OR SHOULD I JUST DO NOTHING BECAUSE I AM CURRENTLY THE HIGHEST BIDDER?
