When I use my with an online merchant, the transaction detail quite rightly does not show a map/location/address. It has grey text that says ‘Online transaction’. However, it does not show the URL of the merchant either. When I’ve submitted data (using the ‘Something Wrong? Tell Us!’ button), the form includes the merchant website (as well as Twitter and Facebook links). But it seems the website data disappears once I’ve submitted it.
It would be very useful if the transaction details could also provide a link to the merchant website. In the future this could potentially be enhanced to link directly to the order details page. I could see this working by either allowing us to manually paste a link to the order into the transaction details page or, (this would require a lot more work!) parsing an email receipt when attaching email receipts is enabled sometime in the future.
In the meantime, though, a link to the merchant’s homepage would be of great help. Thanks!
