I recently saw a thread about things it's worth spending more on to get better quality, but I was hoping to start a discussion about what things it makes absolutely no difference at all with and the lowest priced versions are just as good.
Some of the things I'll buy the cheapest/value version of include:
painkillers
medications
tortilla chips
cleaning products (although I'm starting to wonder about this)
printer paper
disposable razors
cotton wool pads
Would love to hear your suggestions!
