Its not from what i can see.
£79 pounds to get stuff delivered to your door next day probably isn’t worth it (unless your busydog). I think I’ve used next day delivery from Amazon twice in the last 10 years and both times were my own fault for realy poor planning. also bear in mind they do next day delivery for smaller items to an Amazon pick up box in a local co-op, off-licece or corner shop for £2 last time I checked (christmas presents).
TV wise I think Netflix edges it but that depends on what you like to watch
I don’t thing prime has had any big exclusive TV shows and blockbuster film wise its probably level pegging. although Amazon has just bought Clarksons soul but thats not likely to appear for another 9+ months at least.
At the moment i would say cancel it.
if they keep offering people $250 to people to make tv for them then in 12 months the answer could be different
