Because the Amazon API does not provide information on each individual seller and it groups the listings in to buckets instead, the only way to try and compete directly with Amazon using SellerEngine Plus is by referencing the Megaseller price.
In Step 4 of the Reprice Rules Wizard you can choose the "Megaseller price (like Amazon)" option for Referenced Price to compete directly against it.
If on the other hand you want to make sure you're not competing against the Megaseller Price there's a filter that will exclude it if added to the schema in Step 2 of the wizard.
You can also use the Megaseller price in setting up limits and exception rules in your reprice schemas.
For step-by-step instructions on how to set up and use reprice schemas you'll find a tutorial video below:
