RepricerExpress has a built-in feature that will allow you to price exclusively against the Buy Box holder.
RepricerExpress will allow you to 'Beat', 'Match' or 'Price above' the seller in the Buy Box, depending on how your 'Compete with' settings are set up.
To have RepricerExpress do this for you, you will need to edit your Repricing rule and under the 'Compete With' section tick the 'Buy Box Sellers (Buy Box Eligible Sellers)' option.
You will be presented with the option to select 'Price only against the seller who holds the Buy Box spot.' If you tick this second box you will compete only against the seller in the Buy Box.
We only recommend using this option if the Buy Box has a high number of reprices processed. Otherwise, your product may not reprice as often as desired.
If this option is selected, the ability to 'Reprice as normal' will also be automatically deactivated in the scenario 'If Buy Box Winner'. The reason for this is because when you are the Buy Box holder, there is no competitor to compete against.
