You're right, I understand and agree with all of your comments. I did some more digging/googling and came across some more information that's pointing me in the direction that perhaps I've jumped the gun in being too suspicious. What a rollercoaster. I'm going to go through with the sale - and ship the bag tomorrow - though I did ask if I could use UPS instead of USPS. I really want to include that Direct Delivery Only service so I don't lose my seller protection.I'm not going to be as sympathetic and you may not like my comments. I'm not trying to be mean; just stating my opinion.
The buyer paid for the item, the PP transaction says you're eligible for protection and if you ship and get s.c., you're covered. (And having googled, you know the shipping address is a home.)
Why should the buyer agree to the cancellation because you feel uncomfortable? He/she paid and presumably wants the item. If he agrees to cancel, it saves you from an account ding, but I'm not sure you deserve that.
Just because it's a newbie doesn't mean it's a scammer. Some people open accounts because they found the item they want at the price they're willing to pay. We were all newbies once and personally, I'm glad my sellers gave me the chance to prove myself.
And TBH, any trouble I've had has been with experienced buyers and not with newbies.
JMHO.
Thank you so much for your insight.
