Is it risky yes is it more risky than buying on the streets or from a dealer no.
As long as you stick to internal UK vendors then your package will come through unless a postal worker steals it or the vendor screws up which can happen as we all make mistakes now and then.
Buying outside the UK comes with the risk of going through customs but it would seem that some vendors from outside the UK still get their product through UK customs.

Give it a go what is the worst that could happen you get a caution that could happen walking out your dealers house at least this way you have no person to person contact or your dealer thinking you grassed him/her up when you both get busted.
