I posted on 3 April about a life insurance profit deal through CashbackKings
Now paid up and £100 in my bank account! I ended up paying four monthly installments (of £5.01) but received £25 of M&S vouchers in the post from M&S directly. So my "investment" of £20.04 paid out £125 which gave me a profit of £104.96. Result! Went absolutely crazy and spent the vouchers on milk, bread, soup and tinned tomatoes... I live the highlife yes.
The M&S offer is still going for anyone who hasn't tried it, and my next quarry is £60 for Legal & General life insurance - similar deal (but probably without the Marks & Sparks vouchers...).
