If you have a Shopify store, you can add product comparison features directly to your website using apps like Prisync, PriceMole, Compare It!, Product Compare, Compare Products by Omega, Lengow and others. Having a price comparison on your website does two things - it keeps your store visitors engaged on the website, removing the need for them to move to another site to compare prices and also reduces the sales cycle for consumers, helping them make a quick purchase decision.
