Beware - possible hacked or scam website
Went through checkout, completed all card details, then I had an attempted charge on my card for more than the basket value, then was immediately redirected to a Stripe checkout page to pay again for a different amount to a different company. The email on website is blank - I filled out their contact form to ask what happened and for an explanation, nobody replied. Feels like the site is comprised or scammers have hold of it. Beware.
