Should I notify vendor or take a loss?

[katsucats]

I got a plant recently from a vendor whom have sold me otherwise healthy plants. This turned yellow not long after I received it and the stem just disappeared from inside out. It just flopped over, and if I touch it, it feels empty. Naturally I took a picture and threw it out.

Now the question is should I notify the vendor and try to get some redress, or just take it as a loss? Like I said, I've bought over a dozen plants from him and never had a problem until now.
