2-Pack Stick Up Cam Solar Order

I would like to buy two of the subject line items but I am unable to order as they appear to be out of stock on the Ring website, now if I order from amazon.co.uk it will only allow me to order 1 item (effectively I have to place two separate orders) which is going to be £258 rather than the Ring advertised £239, please can you explain: 1. Why are the discounts not applied with Amazon. 2. When will Ring themselves have stock so that I can order directly from the manufacturer.Thx
