yes... it can be really annoying! i would definitely suggest just growing your own. as stipulated in the article, it is so easy. they also grow in the wild. i'm not sure where you live, but you can find them there as well. you could also probably find a really well made product somewhere on etsy searching for elderberry syrup. a ton of great herbalists on there. a little more pricey perhaps, but a good product :)
