Automatic price updateder

hey i’m rick.

just started a website with wp compare theme. i want to make a compare website for all my friends where they should buy there videogames. it’s allot of work but i like it . now i have seen on the internet that there is something called automatic price updater. many plugins let u use ebay/amazone for affiliate compare websites.

now my questing is: can i get something like automatic price updater for my retailers of choise in the Netherlands? without affiliate.
