Coffee

I used to be mostly into teas, but my wife has always been into coffee. I work night shift so I figured it would be nice if I brewed her a cup in the mornings and save her the time getting ready. I've learned a lot about brewing coffee and found a brand that I like but she isn't as into it and doesn't really have a brand she likes. She used to just get a random bag of pre-ground from the grocery store and add sweetener and creamer or almond milk until it was palatable but she's trying to cut down on that stuff.

Does anyone know of a good sampler of whole beans that is somewhat representative of the varieties, origins, and roasts to hopefully narrow down someone's preference?
