Pricing strategies vary for different niches and your business goals. For example Goal for a new business would be to get more customers with lower profit margins while for an established business would be increasing ROI and minimizing ad spends.
I will suggest you begin with doing competitive analysis for pricing, analyze industry standards and set your pricing accordingly.
Here are a few tips!
Don't set round of prices like sett $19.95 instead of $20
Add only 10-15% markup.
Promote free-shipping include shipping charges in product pricing.
Sell products in bundles to increase AOV.
Best of luck with your Sales
