Hi stirfry,
It's always good to do extra research if needed to land the product you really want to sell. Diversifying your product coverage is good too and this will give your customers more choice and you may also get more customers in return.
To help you with that, I suggest downloading your copy of SaleHoo's user manual. Here's what this guide can help you with:
