As a customer of a retail online clothing shop via comment sold
So that I don't purchase an item (same sku) I have previously ordered in another order
I want the application to inform me that I have purchased that specific item in the past and if I want to continue the purchase or remove from order.
Acceptance Criteria:
When I add an item to my cart and or to an order that I have previously purchased
Then I expect the application to alert me that I have already purchased this item, or is a duplicate in the existing order - and to prompt me to remove the item or continue with the order.
