Hi Elana. Sorry you're disappointed with your coffee beans. Personally I would take them back. I have often made purchases that I was not happy with afterwards and I always return them. Sometimes the store says no (depending on what it is) but 9 times out of 10 it goes ok. Just the other day I bought some expensive face cream at Macy's and when I opened it and tried it, it felt much thicker and greasier than the one I'd used before. I looked and saw that I had bought the cream for dry skin by mistake. I was worried the store wouldn't exchange it because I'd already opened and used a bit of the cream, but they did.

Anyway, I do think it's always worth trying to take something back if you're not happy with it. Good luck!!
