Some people buying OS X Lion upgrades via PayPal are being overcharged, potentially in dramatic fashion, according to people responding to AppleInsider and Apple's support forums. In one case a person complains that they were charged about $3,878 on July 28th, the sum coming from 122 individual charges worth $31.79 each. "Apple blames PayPal, PayPal blames Apple," the person says. "They both are claiming to investigate, but I am stuck broke for three days now."
