Shipping costs depend on what it is that is being shipped.
Value of item = $50.00 to $100.00 plus warrants expensive tracked, proof of delivery provided (signature available online), insured shipping as this is what
ebay and PayPal require for seller protection.
Or that is what you charge to cover anticipated loss. Or that is what a buyer wants to cover himself against anticipated loss.
The seller may have put the price higher for international shipping points because of something that PayPal has changed in their rules (I am guessing but they always change things) or perhaps because of discussions on
ebay's forums in the US (just guessing again). Maybe the sellers are not protected when shipping outside the USA and feel they need to protect themselves somehow. Natural feeling.
Regular shipping can be and is, at times, used to cover:
= PayPal 2.9% fee on the amount charged (including shipping) (add 1% extra for overseas sales)
= PayPal per transaction fee of 30c
=
ebay 9% final value fee on amount charged including shipping
= paper invoice or note = 1c - 2c a sheet
= printer ink (draft mode) is 10c black and white (plus tax) or 25c colour per page
= envelope for 5c or so
= shipper's time (sorting, scanning, editing, listing, dealing with happy and unhappy customers
= postage
= tax on items bought at store including postage (up to 15% extra)
= pickle jar insurance 5c to 10c
= cardboard cereal box used as a stiffener to help against folding, bending, spindling and mutilating
= glassine envelope (5c to 10c) or plastic envelope (2c to 5c) to protect the stamps from overly eager dirty fingers and moisture not caused by anything the postal services do at all
= packing tape at times = 5c to 20c
= Scotch tape (clear tape) = 2c - 3c
= the PayPal 2.9% on the extra you added to the shipping to cover the above stuff
=
ebay 9% on the extra you added to the shipping to cover the above stuff
Some sellers cut costs by not including some of the above or including the costs in their stamp cost.
Some sellers misunderstand why the shipping is so high and abuse it and abuse their customers and thus find it harder and harder to sell. Some buyers do not understand (and don't really want to take the time to understand or really should have to) why the costs are higher.
And really, to have a happy customer (notice I didn't say a correct or right customer) you must under promise and over deliver, (or make it like it seems that you are doing so) and act like a friend, be appreciative, try to anticipate and look after customer concerns before they happen, and lots of other stuff, and not bother customers (you and me) with all of these concerns (if you know them). I just want my nice stamps (I have already sold myself on the idea that they are nice) at a reasonable (some people just aren't reasonable!) price.
If you just want to sell your extra stamps you don't want to have to bother with all that extra Work and Thinking and Effort and such. Of course not. No one does really.
Easy. Figure that whatever you sell on
ebay or another site will cost you the seller, about 75% of your selling cost in fees to list and sell and collect money and such. Sell something for 99c, multiply by 0.75 and you get 74c. Easy.
Not wanting to lose much more money, you take the cost of your postage needed to ship the item (including tax) and add on about a dollar. This covers all your costs involved (or should) and lets you not worry about even small loses or mistakes made and all.
So now you are happy and ready set go to sell your stamps and it's up to you to learn how to sell, what sells, how much it sells for, how to present it and title it and describe it so it does sell, etc.
Companies selling stamps have to make money or they won't be here tomorrow. Simple. They have to charge a bit more. No other way it works unless they are getting their stamps for free or something.
Ordinary folks like you and me who are having fun selling and chatting to fellow collectors and don't need to worry about making a lot or any money can afford to take a loss now and then perhaps and it's the friendliness more than the money-making that attracts us. Our time is donated to the betterment of the hobby and general friendship.
And it's
ebay and other online auction sites that allows all of us to be there at the same time, big, small and in between.
It's all good, you just have to understand it and fir yourself in where you fit.
