Great tracking site!! I’ve read the reviews people have put and wow! Intelligence and common sense is not available to a large number of the public. People understand: When a seller provides a tracking number. The seller could be a scammer and take your money and provides a fake number. Write a review on the sellers site. If the shipping company loses the package, then write a review on the shipping company’s site. Track17’s data is only as good as what you provide. They are not involved with the seller or Shipper.
