Yes of course. You can choose either H10 or JS for sales data, so just choose your preferred tool.
If you like JS, like myself and Isaac – perfect!! (we’ve just always used JS, so it’s our preferred).
BUT H10 does have free tools and free chrome plug-in extension for their ‘Profitability calculator’ – you just need to sign up for a free account. (see below – and just like JS, you need to have your browser open to a product on Amazon.com for it to work)
BUT you can use the PAB without this and find your own margin and ROI with your own research.
