What’s the most expensive item you’ve ever bought online? Maybe a laptop, an Xbox, 49-inch flat screen 4K TV or the iPhone X? Or perhaps that holiday you took last summer? Buying online is easy and could not be more convenient. The journey taken for any of these purchases follows a similar course involving price comparisons, checking availability and reading customer reviews before adding to a basket, heading for the checkout, tapping in your credit card details and pressing the buy button. Simple.
