Zdad do you have more in do on the show?
Justsmile for starters you can look at the product reviews (look at how many there are as well as if people like it, look at seller rank (lower’s better). There’s also a website called camelcamelcamel.com which tracks the product so you can see the price history.
Be careful with small margin products because prices tend to fluctuate on Amazon.
(I’m a pretty new seller, so if something here is wrong feel free to correct me)
