There are some differences in the Include/Exclude options you would normally use in RepricerExpress. With Repricer.com, there are no options to exclude by Rating %Feedback Count, Location or Dispatch Time on a standard rule setup.

However, by using the ‘Add Competitor Rule’ (see helpfile here) you can add in additional options to compete differently with different Seller Types, Fulfilment options and Feedback options.

In Repricer.com the standard Exclusions section will have the option to exclude Sellers and Merchants only. 

Repricer.com also has options to exclude Non-BuyBox Sellers, Out of Bounds Sellers (Outside Min/Max), and exclude Amazon here also.
