Amazon have huge fulfilment depots across the country, their systems are incredibly advanced.
They have been heavily criticised for their treatment of staff in these huge warehouses as they have to work hard and fast to get the orders out, staff turnover is high.
I am in two minds about Amazon as clearly there is a need for such a service and they are giving small independent traders a platform on which to sell, however all those white vans delivering all those parcels it cannot be environmentally friendly.
My son works for Amazon overseas and so far has had a good career with them so I a bit biased, also I love Alexa!!She is my source of info, music, oven timer and telephone!
