Re: Local Pickup desired, but PayPal charges shipping.
For local pickup and delivery I usually use a delivery app like Phlatbed, it's like Uber for Facebook marketplace local pickup. I include it in the transaction when I'm selling, or factor it into my bid. Once we agree, then via the Phlatbed app I can arrange pickup without worrying about dealing with PP or the other side.
If it's in my neighborhood I simply driver there or meet halfway somewhere. Image below from another poster.
