I am feeling really lucky at the moment. After being offered £20 co-op vouchers when I renewed by insurance I was happy. Then I had a win on the premium bonds. I complained to Waitrose about a product that was not up to their normal standard and they are sending me vouchers. I even was sent a free gift from Lego VIP program. This was an exclusive Valentines keyring which I am selling on ebay and seems to be very popular. That should raise some unexpected cash. It may not be a fortune but it all adds up and is better than getting nothing.
I firmly believe that having a positive outlook in life, like I have, can really help with getting opportunities like this.
