Target A Seller

If you want to reprice against a specific competitor, you may configure the Amazon merchant ID of the competitors under the "Settings-->Repricing-->Repricing Model-->Seller" tab. This rule would work good with Amazon's latest Subscription API only. Click here to migrate the repricer to Subscription API. The "Seller" tab of the SKU should be configured as below:

'Against' column should have Amazon merchant ID of the competitors
'What to Do' column should be selected to Raise By or Lower By or Match or Ignore as per your requirement and click on the 'Save Seller' tab on the top right of the screen.

If you want to add number of merchant IDs, simply click on the green color box on the right-hand side with + sign to add additional rows after filling in the existing row.
