Brighter Blooms Nursery review: Cross vine that dies

We purchased 4 $50 cross vine plants and within 40 days one had died; I was told that I could buy a warranty for $50 and they would replace the vine but their warranty is only 30 days. It took that long to make sure it did not survive as it was not healthy and we gave it a chance. They will not stand by their product and they will not replace the vine unless I buy the warranty.
