Yeah I agree Kate with the shopping around thang...You definately have to know your prices on certain things otherwise you do get stung with postage costs...
I just love the fact I can buy unique handmade jewellery from overseas...and know that no 1 else will have the same things as me
And I've also found I can get heaps of awesome Hello Kitty stuff online as well!
Its a shame you got stuffed around when you tried to sell things, I've heard some horror stories from some people! I'm lucky I've only ever had one drama, and I got a refund through paypal so it was all good!
My step dad sells mobile phones allllll the time on ebay, and makes a bit of a profit on the side. A guy at my work was telling me a friend of his makes around $500-$700 a week through ebay, I'd love that!
I just love buying things online...saves me going out and it gets delivered straight to my door
