I placed an order for three items just prior to the December rush

I placed an order for three items just prior to the December rush.They arrived before the promised date, which is always nice. One of the items sent by their supplier was incorrect, due to close similarities between the products. They re-ordered the correct item, which I received, today. Their supplier allowed me to keep the item sent in error. How can one be unhappy with that? Thanks Dealsdaily!
