This is my take as a seller.....
COVER YOUR BUTT!!
I used to charge basic shipping w/no tracking....
Seems that once the buyers realized that about 10% (yes!!) was coming
up missing. You know who loses...the seller.
I got tired of that.....
I raised shipping to $2.50 (combine extras for free)....
postage with tracking $2.54 + sturdy envelope, etc....
I lose on shipping (also
ebay does take a cut of this)
BUT......NONE has come up missing since.
Does the shipping affect bids???
Probably....
But not nearly as much as the multiple refunds.
Now with the tracking.....
I am a TOP-RATED seller....
I even get lower listing/selling fees but also
20% off of
ebay selling fees.
The end!
