Sure if she'd rather meet by traveling to a public place than pay a shipping fee. I know if I were a woman I'd think twice about a stranger off ebay delivering things to my residence even though that stranger might already have my address for shipping. Then again a lot more women own guns these days.
Violating ebay/paypal protections? Dunno I haven't read the fine print in years, but I have bought items on ebay, paid with paypal, and it was for a local pickup... I often check local pickup item listings to see if there's something I can get dirt cheap in my area, then feel bad and give them $5 for gas to meet me if I won an auction for $1 because they didn't set a reserve.
