I proudly pad my shipping costs a couple of bucks. On the other hand i have lost money on shipping as well.
Many people pad the shipping costs on E-Bay though, i think its kind of unfair to complain since E-bay has lowered the prices on what we want to buy so much. Before
Ebay, camera products could only be bought from a dealer, or a privite party via advertisments. The equipement is so expensive in the camera shops that many people wouldn't get into this hobby without a place like
Ebay.
I personally wouldn't pay 900 dollars in a camera shop that i purchased awhile back on ebay for 400 dollars. I never would have gotten into the hobby at camera shop prices. Probably wouldn't have at used pricces in ads either.
When i am paying half price or better for photo equipement, i can't find it in myself to complain about a slightly inflated shipping price.
Additionally shipping is expensive. It keeps going up every yr. When i first started selling on Ebay a couple yrs back i thought it was expensive to send something like a dvd player accross the country (US postal about 10 bucks). I sold one on Ebay about 2 months ago, 10 dollars for the DVD player, and 20 bucks for shipping. I thought i was padding the shipping too much but when i got to the post office it took every bit of that 20 dollars to ship it. Sure it might have been cheaper UPS, but i was shipping alot of stuff, and UPS is expensive for little things, plus unless you have a bussiness, UPS is less convenient. Shipping is expensive anyway you look at it.
