Postage charges

[Lily]

Hi there,
I just posted something I sold through Etsy and thanks to an answer I received on this forum previously I knew that jewellery is not covered by recorded delivery but only special delivery. That cost £6.45. Although in this instance I charged the customer £4.45.
I just checked what other jewellery makers seem to be charging for postage on Etsy and it is much less on the whole (at least the ones I looked at) charging around £3. Obviously they are not insured.
I am wondering what any of have decided to do when posting? I am concerned that the high price for postage might put some people off buying.
Thanks

Whoops - sorry - I just found an older thread which answers my question in part, although opinion seems divided on whether it's best to include postage in the price of the item. I would still value your opinions please. Also the PO ask what is in the package now so this may make a difference.
