The data is very accurate when it comes down to price comparison between different stores in your area or country as well as with other online retailers that you are not familiar yet.
Their customer support team can be quite slow at times but they do respond eventually once contacted them via email/phone call. I have used this service many years ago back then i was working from home without any office staffs around me therefore my work load became heavy especially during weekends which made communication difficult sometimes due to lack of internet connection. This helped ease some pressure off because now we don't need an employee who will help us out while doing our job remotely since everything has been taken care already!
