The public mobile orchard link https://publicmobile.getorchard.com/search/index/ does not show as many options for purchase as the normal public site https://www.getorchard.com/ .For example - at this time no iPhone 5S is available and no option to even set an alert to watch for it (grrr).
The publicmobile orchard site only has refurbished phones and I understand the rationale, but given we are a frugal bunch by nature I think we should at least have the option to buy phones in other conditions (at our own risk) and at a discount compared to the general public.
