£30 connection fee still not mentioned in thread cost & title at time of this post. And the OP statement of "but there is no minimum contract term on this product" is incorrect as the minimum term is 28 days.
I don't post deals often so I might be mistaken, but I didn't do any 12m calculation in any post or the title. I can see it's been put there now, but not sure who by.
Arbitrary minimum 12m cost mentioned in prev post in line with the deal title that quotes incorrect 12m cost of £288, not the actual £318 cost.
Maximum cost I'd say, but in any case the 12m is an arbitrary term. I'm usually not in it for a quick cashback buck, but as a bridging provider it sounds quite useful.
Fair observation. So minimum cost over 12m is £30 connection + (12 x £24) = £318.
