I've just had someone at the door selling cleaning products. Answered the door holding the baby. Stupidly in a panic to get him away I bought 2 things for £10. Now reading all about how this is a con (which doesn't surprise me) but also that it's used by criminals to find houses to break in to. Now I've got myself in a bit of a panic, DH works away a lot so it's just me and the baby so I feel quite vulnerable! Are these often a criminal group or are they often just people who have fallen on hard times?
