To prevent PayPal unauthorized scam of collection items, can you post a dummy letter tracked?

[infinite900]

Hi hope all is well, first time in 5 years I'm having to post on the forums, a buyer insists PayPal payment for collection item, I won’t make them pay by cash or I could get negative feedback by them, is it true that PayPal reject INDescribed or INR cases for collection items as the buyer can see it there and then,  

but I've had it before payment not authorized. I am waiting an additional day to prevent this happening, but what happens if I post a dummy letter on the day of collection tracked in case they post a unauthorized payment claim and get refund, can I give PayPal the tracking number if they ask for it if a Unauthorized claim arises to prevent the funds leaving my PayPal account? Is that allowed 

I don't want to be scammed here but I stated clearly buyer pays COC, they paid by PayPal,

if I refund I'll get Neg Feedback

The buyer and I have agreed I will now post the item with them via courier service at my expense .

Trouble is that you cannot refuse paypal, and buyer can open a Not Received Case to get a refund.

If both buyer and seller are using the Ebay App, the buyer gets a code from Ebay which they showto the seller who scans it with their phone and that marks as collected.

Unfortunately the chances of both parties using the ebay App. which from what I hear is pretty useless is remote.

I could not agree with your suggested means of getting protection, it would get you into serious trouble with Ebay if brought to their attention.

The possibility of a buyer trying it on are pretty remote, but it has been suggested taking a photo of the buyer with the item and their car, would work as a deterrent. It would not prove anything as far as ebay are concerned, but could be useful if taking legal action.

Sure , but without proof of postal delivery, why don’t I send the receipt or something tracked Mail? I don’t think PayPal will know or care what the tracked Mail was, will that cover me ? Thanks for your comment ,
