I have made commissions from SaleHoo in the past. It is a useful product to promote in the eCommerce niche. SaleHoo is a great service that is still in demand. It also has longevity and has been on the Clickbank platform since the early 2000s if not longer. It converts well as I have made several sales myself recommending it on one of my own niche websites.
That being said, I do recommend promoting this product with a niche website. That is how I got my start in affiliate marketing and what I continue to do today to run my online business.
