I am thinking of selling electronics, but am worried about these paypal chargebacks.

I have read here that buyers were filing chargebacks against honest sellers after receiving their products, and paypal awarded them the money.

Even if the sellers provide tracking, is it possible for the sellers to win the dispute??

What if the buyers used a credit card? Even if paypal favors the sellers, can the buyer's credit card companies force paypal to take the funds from the seller's account?
