I need something like Keepa with sales estimator (most important), price and buybox history.
Dataspark is best for Walmart, similar to Keepa. You can also use Ecomcircle as an FBA calculator.
I am using Marter, it can be highly recommended.
How is it? I am using DataSpark.
I like layout better than Data Spark. It is cheaper than Data Spark. I usually do test buys according to the number of sales listed on Marter before placing the large order.
I am not sure how accurate the sales estimator they offer.
For an example if it show 5 sales per month is it will be real something like that?
For such low volume listings how good Marter estimate the sales? Is it really can be 4 sales/month or may be a zero?
This is strange because I checking the brand I sell on Amazon, on some listings we have 400+ sales, but on Walmart it’s only 3-5 sales.
I generally do test buys to see if that sells on Walmart. Walmart does not share its API so these numbers are unpredictable. I generally go by verified sellers reviews.
