You come across an offer on the internet that appears too good to be true. Due to a typo, that beautiful laptop carries a price tag of 150 euros instead of 1500 euros. You quickly decide to benefit from this deal and decide to purchase the laptop. Can the store then still cancel the sale? The answer depends on how much the price differs from the actual price. When the size of the price difference suggest that the price cannot be correct, the consumer is expected to investigate this price difference to some extent. This can be different in case of price differences that do not directly raise suspicion.
