"We live in not so distant cities."
I guess it partly depends on how far away you are - do you consider your time = money?
If the meet is a short distance for you it might be worth while.
Pick a public place, in daytime preferably.
Bring a friend if possible.
I have done "self pickups" in public places occasionally with no issues.
If you are still uncomfortable after considering above then onus should be on the seller to correct his/her mistake.
Not sure though if ebay policy requires you to pay for item shipping by mail if refund is warranted.
