When I don’t wear my glasses shopping I always end up buying something that is not exactly what I wanted to buy. Such as coffee that is NOT grinded. How annoying, it was when I realized that 2 out of the 4 packs of the 8 o’clock coffee purchased were filled with ungrinded coffee beans (the Whole Bean) 🙁 
How was I going to get the beans grounded up? I do not have a coffee machine with a bean grinder!
Then I did a web search and found that to get the beans grinded just put them in a blender. Ha! They knew exactly what I needed to do. The question was would it really work or was I just going to waste two packs of coffee…
Oh, how happy a blender could make you. When it turns coffee beans into coffee.
