Competitor price monitoring can help you react quickly to shifts in pricing and prevent losses. It can help you drive more sales to your online store since you are able to avoid overpricing products. But a few online store owners are taking advantage of price monitoring. What they don’t know is that they may be selling their products too cheaply and getting a narrower margin that their market allows. So if you just set up an online store, the first thing you need to consider is to track competitor prices.
