Looks suss to me.
FWIW. I am concerned that ordering online for a rally flag or other merchandise here that the connection is not secure. No green padlock visible. With the amount of data breaches occurring worldwide, this is a worry. Rest assured that no site is immune from the "hackers" and the techniques used to pilfer as much of our personal information and data is always being refined. So too the techniques to breach data centres.
In addition, when the USA IBA team were still doing the this, I had a IBA verification payment go west when I applied online via the IBA eStore some years ago. I knew something wasn't right when I clicked button for that final step to confirm payment. Screen flashed a couple of times and then I was sent back to the starting payment screen. I then logged out with my job to follow up if payment was made.
The next day I received a call from my bank asking if I was in Nigeria. Um, no, haven't left town said I. They could see that the payment was being processed over there and fortunately, the bank reversed that transaction so I wasn't out of pocket.
Err on the side of caution is my advice.
Again, I do have a major issue with sending details over un-encrypted connections, I simply refuse to do so.
