I pay £22 for my iphone & £15 for a sky package. I don't know why people think these things are extortionate
Because many people are paying three times that amount for an iphone and a hundred pounds a month more than that for a Sky package.
Unless you can see what is going in and out of someone's bank account, you have no idea what they spend and people with lifestyles that on the surface look very similar, can cost massively different amounts of money. Also, if you shop around, use discount codes etc, you can get exactly the same products and services for significantly less.
A smartphone and service can cost anything from about £10 a month to at least £60. I got a fantastic Black Friday deal 18 months ago on a Moto G7 that cost me £75 after cashback and is still working perfectly today. I don't foresee changing it any time soon. I sold my old crappy Huawei on ebay for about £60, so it cost me almost nothing to change my phone. I pay a fiver a month for the phone service.
People with full Sky packages can be spending £100+ pm, or you can get a couple of streaming services for £10 ish a month each. There's huge room for negotiation with most of these. If you want Sky but don't want to pay full price, you can reduce the cost significantly if you phone and threaten to cancel.
We've got Now TV movies and Prime currently, having just swapped Netflix to Prime, for a change. I don't see any point paying for more than that, as we don't spend that much time watching it. The movies is currently on a half price deal and when this comes to an end, I'll ask for another deal and cancel if they don't offer one.
With many cars, unless you actually look at the number plate, many new cars don't really look any different to a 10 year old one at a fraction of the cost, so you'd not always notice if someone had a new car or one that's cost them much less.
There's endless examples like that, but just in the above three, someone who does all these has a smartphone, a car and a TV service, but there's a huge difference in what it costs.
