Button on listing page.

I thought I would give datafeedr another 6 month trial after being reasonably happy with how Amazon has been converting over the last six months but I have hit an issue.

The button on the category page items – https://hpj.co.uk/listing-category/stud/ – tries to put the item into the cart. I don’t want to use a cart, I would like the buy it now link here, which is what happens if you actually go into one of the items;

How can I achieve this? Thanks!
