Alpha Foods Plant-Protein Crispy Chik’n Patties, 10 x 3 oz

Can someone please tell me why you rarely have these chicken patties at my local Costco in Lafayette Louisiana 70508? I will go one time and they are there and then a month later I’ll go and nothing and a month later nothing then a month later they are there. Am I just not going soon enough and they are selling out or are they being discontinued? Thank you, Lisa H
