HI welcome to the wonderful level playing field called ebay / paypal

When you post you need to obtain proof of postage and that will have a tracking number.

With that you will be able to see when it is delivered.

You need to lodge every item at a post office as items in satchels via post boxes are not traced.

You need to get a supply of  DO NOT SAFE DROP stickers to add to every parcel as without that attached you will find that about 20% of your items will never get delivered. (not stolen just not received by customers)

To be honest if you do not use registered / trackable  post you will need to increase your prices by about 20 % as that is what you will lose in "theft" "false claims" "undelivered items"

My personal record was five claims for non delivery of a fifty dollar item sent registered post, four claims were granted by paypal until I lodged the buyers signature on a run sheet, the registered post details and a claim to the ombudsman for fraud against the buyer and paypal Then it suddenly was granted in my favour.

Sorry to be cynical but there are a lot of scams going on out there and most of them are by buyers nowadays.

And also keep an eye on your DSR as the shonky ones leave low ratings for you anonymously which can impact on your ability to list on Ebay.

Merry Christmas to all.
