Q: How can I use the estimate price button, with or without supplier shipping?
A: When using the estimate price button, you would need to first add the supplier price + shipping together to get a total item cost. Then plug that number into the estimator. The estimator is merely a calculator and is not reading your supplier shipping. Whereas, when Sku Grid does it's repricing, it will factor in whatever shipping is scraped and insert it where the vendor_shipping variable is in the formula.
So for example, if the supplier item was $100 and the shipping is $5.99, when estimating price with include supplier shipping in calculations set to Yes, you would input 105.99 into the estimate price pop up instead of just 100.
