We see too many sellers put the option for tracking and then go on to say in the description "I cannot be held liable for gone missing during transit if tracking has not been chosen"

PayPal does not care if the buyer chose regular post over tracking post.

I personally always choose regular post when its offered because A. it is cheaper for me and B. I will always get my money back for items not received.

Also, comments like this make me laugh too (which i still see a lot of) "Please do not bid if you do not intend to pay, we will be forced to leave negative feedback for buyers that bid and do not pay"
