I would DEFINITELY return the oil, even if you used it a few days already. What is the expiry date on it?
I would also never buy this oil unless refrigerated. I guess you could ask the store when they get new delivery, then pick it up right away.
The other thing you could do is contact the distributor at florahealth.com and ask them for a store in your area that they know to carry this product refrigerated.
Good luck
