i need to scream

It make sense to buy something expensive if its expensive you expect high quality granted there are some low price quality goods but it makes sense to buy something expensive and to use it 10 to 20 years down the line. I feel its common sense rather than buying something that rather cheap, and buy two or three within those 10 t0 20 years. On average people only use their good for 8 years and sometimes less, so if a good last 10 years and its expensive then its worth it, it out lived the expectation.

So do i need to scream because I am angry at my partner because hes always buying low price goods but several times every 2 to 3 years, which is costing way more than buying one high quality good and he doesn't understand where I'm coming from. Which just frustrates me.
