There are various benefits to buying financial products online - particularly ease of comparison, selection and application! You can use the power of `supermarket` sites such as Moneysupermarket.com or financial information sites such as fool.co.uk to find out what the latest best offers are on financial products which interest you. This saves you having to trudge around the high street comparing the latest offers, and you can do quick and simple online comparisons between different providers. Online offers also often offer better rates - such as higher interest rates on online banking or savings accounts, or 0% credit card promotions.

Another way to save even more money is by purchasing these financial products via a cashback site. Cashback is a relatively new online phenomenon which rewards online shoppers for purchasing goods and services online by offering special incentive or cashback sums of money. Members of the cashback sites will click through directly to the service or good that interests them to qualify for the cashback. The sites will have new and different promotions each month (they earn their money through online referrals to the sponsoring companies.) There can be some great cashback promotions on offer - particularly for financial, insurance or banking products. For example, some credit card applications can earn up to £25, car or home insurance products may attract cashback of up to £70, and even current accounts can attract around £40 for a successful application via a cashback site. Generally most of the big financial services organisations will have cashback offers at some time - and you can factor the `free money` when selecting which financial product is right for you.

There are various sites available - some popular ones include Quidco, Topcashback and Greasypalm. Each site is basically offering a similar service, but rates of cashback may differ - as well as tracking times and customer feedback. You may wish to sign up to several sites to keep abreast of the best offers. You will need to sign in at least every few months to ensure that your registration doesn`t expire and the cashback payments take around 10 weeks to track and pay. Payment is made generally via BACS bank transfer or through Paypal, depending on your preferences. You can also leave feedback about the cashback provider and the company that you`ve bought your services from. This is an important element of the cashback experience and helps other customers decide whether to take up the cashback offer.
