No harm in getting finance for a pinnie.. TV.. sofa or anything else you want to pay for over time. Personally i dont like finance and steer clear of it but my wife handles it all very well and gets a lot of 0% over 12 - 24 months. Its always paid up in time and leaves the bulk $$'s in the account.
The link i posted had 0% for 6 months.. thats an ACDC paid for over 6 months at no extra cost... now why wouldnt you?
