George Zimmerman will now make $100,000 more than anticipated for the sale of the gun he used to kill Trayvon Martin -- because he got a much bigger offer for the 9 mm weapon.
Zimmerman had reached a deal with a Florida bar owner to sell it Friday for $150k -- but at the last minute Zimmerman pulled the plug when he found out someone else was offering $250k.
Sources connected to Zimmerman tell us a female bidder contacted his attorney Thursday to make a deposit. Zimmerman initially didn't take the offer seriously, but we're told her funds were verified before the auction ended.
We're told it's now a done deal at the $250k price tag. Still unclear if the purchaser will remain anonymous.
