UK question

i was wondering if any of you had been caught getting weed sent to your house in the uk i recieved a sample off of a supplier and i am now going to buy an oz off of them it will be double vacum sealed the same way as the sample < will this reduce the chances of it being caught through customs. Because someone i know said that a freind of theirs orders a oz everymonth from amsterdam and he's been caught 3 times by customs and had pigs come to his house< im not sure if this is true but can anyone clear it up for me are they likley to go to your house if they find it?im not getting it from holland so will this affect the chance of being caught with it? i thought it's be less since the country im getting it from it is illegal there aswell.
