Finally managed to get my head around the various hurdles caused by the postage price increases, and re-opened my Etsy shop. It has involved ordering new size mailing boxes, researching other options for the "medium size" parcels and (unfortunately) raising prices a little.
I'll still be using Royal Mail - First Class for small items and Special Delivery for high value (£50+) items.
For overseas items, I'm sorry but the situation is pretty dire. Royal Mail has cut the compensation cover to £20. For smaller items, I'm happy to risk it so that's not too much of an issue. But for medium and large items I have to use Airsure, which I'm afraid really bumps the price up. I'm thinking that maybe it would be best to offer 2 options - one without the extra cover and one with, then people can decide if they want to take the risk or not themselves.
As you'll see, I have not listed any items with combined shipping prices, but will refund any difference via Paypal after posting.
Postage on cards and postcards remains the same!
