The problems I identified on the page were mainly:
Swiipe defined the styling of the page, meaning that the look of the buttons and how the products are shown does not match the page it is on. This risks the customer believing this is something else, not directly related to the site they were on.
Right after the order confirmation Swiipe advertises their own service. Because this stretches over the whole page, we might risk customers that do not think this is relevant to them stopping their navigation of the site there. That would mean they do not pay attention to the products below.
The colour of it is grey and not very eye catching. By having the headline centre aligned it might not be as noticeable since it does not match with the text above. That could mean the user would miss the headline, and mistake it for something that might not be relevant to them, like the Swiipe ad above.
Not only do the products not match the website it is on, they are also very cramped together on the left side of the page.
