Cheap to me means having to make do or not knowing the difference between value and cost. Inexpensive to me means in relation to the value you are getting from the product.
I buy cheap when the product doesn't matter to me whatsoever, like toilet paper. I refuse to spend high dollar for something that is flushed down the sewer. Northern 1000 sheet rolls is what you get at my house or bring your own. When it comes to food I won't buy cheap if it is not the best quality.
