Online shopping is as safe as you make it. You must do some homework on who you purchase from. That doesn't mean you have to go through loads of good guy bad guy reports, it means that you have to tread carefully and be aware that there are some dodgy dealers online waiting to gain possession of your bank details, which will arm them with the information they need to rip you off. Be aware of dodgy dealers and unbelievable bargains. Most reputable online retailers will have security measures in place.
