,and beable to offer free shipping .
That's disconcerting.
Any seller can offer Free Shipping.
It just means you are including the cost of shipping (and packaging) in the asking price of the item listed.
Which is cheapest?
A $5 item with $10 shipping
A $10item with $5 shipping
A $15 item with Free Shipping?
Same price to the buyer, but for the seller the last ($15+FS) is cheaper because there are no FVF on shipping even on international/US sales where you do charge shipping.
Shipping FVF are based on the first domestic shipping fee. If that is 'free' then there are zero FVF.
And you do know you get discounts between 5% and 17% off from PO counter prices when you buy certain shipping services through Paypal, right? Again, any seller gets these discounts.
