its true that mistakes happen
on the other hand, its also true that companies need to invest in processes and well motivated, well paid and competent staff, and that investment helps prevent mistakes happening. Automated sales systems like this decrease staff cost and overheads, why should this be risk free for the seller?
The ease of *ucking up pricing on the internet and losing out as a company is a fair counterbalance to the overheads and risk of running a retail premises – we all know that small local jumper shops can’t match the prices of people running their business from their garage or a lockup because of the overheads – well, if the internet sellers run the risk of losing out like this then they would have to invest properly in staff, and that levels the playing field.
