Price Not Accurate

I started using this plugin because I didn’t want to display the wrong price on my site and get banned from amazon associates. However, even with this plugin, the price is not accurate. For example, a product’s current price on Amazon is listed as $381.12, but my plugin is listing the price as $365.40. I did some digging, and it looks like it “may” be grabbing a price from another seller who has it listed as $365.40 + $63.00 shipping. Is there any way to make sure it shows the actual current price that the link points to?
