My team member or VA is getting different Buy Box than I getting on an Amazon product page

Your VA will see a different buy box price being displayed because of one of the following reasons :
  1. The delivery to the zip code you are using does not match the delivery to the zip code the VA is using
  2. The VA is logged into an Amazon buyer account that does not have prime and you are logging into a Seller Central account that has "prime" delivery being used 
  3. The country or location of the user calling Amazon is different from the one you are using
