UPDATED: Willing to make up for their mistake
UPDATED REVIEW: NSS approached me after I left a 1 star review, their sales manager Shirley is quick to come up with a good solution to compensate my customer. They have issued a $10 refund for all the customer affected by late delivery. They also promised to issue full refund if the delay is more than 30 days. I am going to continue working with them and try out their new shipping channel.
