The problem with free shipping is it deters buyers from making multiple purchases to save on combined shipping. If a seller has a reasonable combined shipping rate I will be much more inclined to browse the rest of their items vs paying an extra $2-$3 per card because they included the ship price into the price of the card.
I charge $2 + $.25 each additional with a max of $3.50 or free shipping on purchases over $50. I also carry a solid 5 star rating. Maybe I've just been lucky I guess.
Smart buyers bid by total price. My only real pet peeve on shipping price is sellers who charge $3+ and then send in a pwe.
