Default Price for all items problem

Hi,
recently i paid for a site to be converted to wordpress for east management and the integration of woocommerce seems faulty. When i click on any item:
romafruitsofnature
all the products have a default price of N31,000 and i cant seem to find where the problem is so i suspect it was coded into the plugin and i cant seem to reach the developer. I really need a fix on this urgently thats why i came here to see if anyone with extensive knowledge in coding can help out thanks
