solution to paypal chargebacks so u dont lose money

OK IF YOU HAVE SOLD MORE THEN 100 ITEMS THEN I'M SURE YOUVE HAD A PAYPAL DISPUTE FILED AGAINST YOU. I HAVE A SOLUTION TO FIX LOOSING MONEY OVER THIS. WE ALL KNOW WHEN A DISPUTE IS FILED WITH PAYPAL FOR ANYTHING OVER 35 DOLLARS PAYPAL WILL HOLD YOUR MONEY FOR 30 DAYS JUST TO TELL THE BUYER TO SHIP IT BACK FOR A FULL REFUND. AND IN ALL REALITY YOUR JUST OUT THE INITIAL SHIPPING COST. WELL AFTER A DISPUTE ON A MOTORCYCLE ENGINE I SOLD FOR 75 BUCKS BUT IT COST 375 TO SHIP. THE GUY FILED A DISPUTE WITH NO INTENTION OF SHIPPING IT BACK JUST TO BE SPITEFUL. THERES 2 ANSWERS TO THIS PROBLEM, 1ST SHIP THE ITEM C.O.D. (CASH ON DELIVERY) OR CREDIT FOR UPS. THIS WAY THE SHIPPING COST DOES NOT GO THRU PAYPAL AND YOUR NOT OUT THE EXTRA MONEY. ALL FREIGHT CARRIERS DO THIS UPS DOES THIS. THE OTHER SOLUTION IS HAVE THE CUSTOMER PAY THE SHIPPING gePANY DIRECTLY. A SEPERATE PAYMENT TO THEM CANT BE DISPUTED THRU THE TRANSACTION. THIS WAY YOUR NOT OUT THE COST OF SHIPPING AN ITEM IF FOR SOME REASON THEY RETURN IT. I'VE HAD PEOPLE BUY A WORKING LAPTOP SYSTEM FROM ME, TELL ME THERE WAS NOTHING WRONG WITH IT THEY JUST CHANGED THERE MIND. NORMALLY THAT WOULDN'T BE A PROBLEM BUT IT WAS PURCHASED RIGHT BEFORE X-MAS. THEN THEY DRAGGED THERE FEET RETURNING IT AND IT SHOWED BACK UP 2 DAYS BEFORE X-MAS. WHEN I WENT TO RESELL I TOOK OVER A 100 DOLLAR LOSS. JUST SOMETHING TO THINK ABOUT. NONE OF US LIKE DISPUTES, BUT WE ALL KNOW THERES PEOPLE OUT THERE WHO CANT BE REASONED WITH NO MATTER WHAT. GOOD LUCK
