From reading other posts, there are often technical problems with PayPal postage

Just recently I started to use the postage labels via paypal for sending out but now I'm told that 'The selected service type is currently unavailable' when I try and create a label for a recently sold 400g packet.
Anyone have any ideas? It seems to be within the small packet dimensions and limits. I've tried standard 1st class & recorded without success.

I did do a search on these forums but the search facility on here is complete carp.

You could try deleting cookies/cache etc., and try again.

You can also print postage on the R.M. wesbite, but they don't accept PayPal.
