honestly its stupid people even charging shipping fees, you dont save anything on fvf, you rank lower in searches and you get buyers whining about the true cost of shipping vs what it cost. i roll my shipping into product cost and offer it free but i always add on more than shipping costs. if you charge the actual shipping costs your losing money as your paying fvf on the shipping costs plus you have to account for your time, gas to post office and packaging materials. in the situation just described i wouldn't be concerend about shipping costs as buyers should look at total product cost period whether shipping is seperated or rolled in. that said if someoen doesnt package something up well and its damaged or open during shipping thats bad.
I wouldnt have negged for the shipping costs alone , but the overcharge combined with piss poor packaging and the response i got from the seller about it (he pretty much told me to politely go eff myself) had me smiling and calling him a bastard as i hit the neg button
as for putting shipping costs in the price of the item some times it works for me and some times it doesnt
on something big like a bicycle ( i ship 2-3 every year) if i ship to my next door neighbor its going to run $25 if i go across country its going to be around $75 its difficult to tag that on the price
other items if i tack a comfortable shipping cost on the item sometimes it drives up the cost to a point where it looks silly ive sold many things for $25 + $25 shipping where as the same item would sit for months untouched at 49.99
free shipping
that being said if i can ship first class mail of a small fr box or envelope i put them up free shipping
