The biggest problem is postage costs SUCK. Plain and simple. They are just too damn expensive. Buyers don't understand this and they tend to take it out on the seller. You sellers, look at your "star ratings", notice how "shipping and handling" is your lowest value even though you don't screw your buyers by trying to profit on the shipping?
International buyers are the most pissed with the elimination of surface shipping. I just won't ship internationally anymore. When I get emails asking me if I'll ship to Europe or Asia or wherever, I basically say "sure, if you're willing to pay $75 (for example) for the postage". I never hear from them again.
Buyers just are unable to cope with the shipping costs. 1 pound flat rate is now close to $5. A few years ago it was $3.25. Oil, blame it on oil, and greed.
On another note. Good bye Meg Whitman. I for one will not miss you. Good riddance.
