Hi, well I have lost in shipping quite a few times, although the best way I have found to do it is by the calculated shipping. I bought a set of postal scales, I get the item, and the box it will be in, and weigh it. then I add a few ounces for the weight of the plastic, paper, or bubble wrap that will be used. All prioirty boxes are free, although the shipping costs are still based on weight and zone. NO special rates, or discounts. I print my own labels online, that way it saves me the 45 cents for confirmation when shipping priority.
Now I like to offer atleast two shipping methods which I loose on alot also, cause when parcel post is chosen, I then have to pay for the confirmation!
Either way, you can make money, but unless you think of a quick get rich item, you dont get rich. I just barely clear money! still trying tho!! :lol:
