In the end, people don't like paying the worth of a product. Instead they opt for "cheap", and when the item they purchased doesn't work for them, they go ballistic.
That doesn't mean that cheap items are not good... but I have seen time and time again someone pay, say, 25L for a product instead of the 500L version, and when the 25L version doesnt fit, or work, or has issues. they rip the creator/seller a new one.
If you don't want to buy the higher priced item, don't buy it. If it's something you really want, and its a reputable seller, bite the bullet and pay for it. You probably won't regret it.
