Live Price comparision

Dear Community,

I’m working on a new WordPress website to compare different prices from different websites, so customers have a good overview where to buy there products for the cheapest price. My is issue is: until now I haven’t found a way to compare the prices of different online stores with a plugin or something similar. I’m a noob at coding so I would like to know if there is a easy way to manage this.

To be clear at what I would like to achieve.
On the websites below it’s possible to buy an Ipad for different prices.

I want my customers to see both prices on my website so they know where to buy it for the cheapest price.

P.S. It would be great if I am able to manage changes of the prices live, so when there prices change my website doesn’t show the previous prices.

Can someone help me?

Thank you in advance!
