The website of the UK’s largest gift card service, One4All, is not accessible from Apple Macs using the Safari browser, or from iPods, iPhones or iPads using Safari. Their website is here.

However after several days, the situation has not changed.
Mac owners using the Chrome browser can access the sight without trouble.
