Ordering in juno.co.uk

Hello! Has anybody tried ordering thru Juno? I placed an order and it was shipped thru Royal Mail First Class Air Pro which uses a non-trackable service. I’m a bit anxious if I would actually receive my records. Juno offers insurance in case of lost or stolen items. Only problem I have with it is how would I know if it were lost/stolen if it is untracked.

Any help/advice on this would be appreciated. Thank you.
