To be fair what DH has said is what you should do.
I have paid for things via bank transfer to members of the forum. There are many people on here you can trust.
I put £280 into someones bank account via bank transfer

in fairness though i have met this person face to face before and purchased stuff from them in the past.
So there are people that can be trusted.
People that i have dealt with and would deal with in the future are coincidentally the ones with higher post count.
