One seller account can be connected for each region. In Tactical Arbitrage, three regions are listed on the Authorization Page: North America (covering the U.S., Canada, Mexico, and Brazil), Europe (including the UK, Italy, Germany, Spain, France, and India), and the Far East Region (for Australia and Japan).
For example, if someone has three seller accounts—two for the U.S. and one for the UK—they would be able to add one U.S. account and the UK account to Tactical Arbitrage.
