Does anybody use zero interest balance transfers on credit cards as a means of cheap credit. I put 8k on my credit card 12 months ago for some home improvements. It was zero interest for 12 months so happy days just pay the minimum 1% repayment each month. So this month I transferred the remaining balance circa 7k onto a new card with different vendor for another 12 months interest free. Obviously I never used the card for anything else in the period and no clue what my card number is. I don't plan on using the new card for anything else either. I could easily pay balance off from savings but since its interest free. In another 12 months plan on rolling it again for interest free promo so that will be 3 years interest free.
