I just did a search for Rosary and a banner ad came up. It has 3 different Rosary showing.
Are you being singled out or did they take the buy box from your. Check you SC page and see of the listing say buy box eligible.
Just looked and 60,000 Rosaries surface from that search query. More than likely another seller is being drip feed sales because they did not sell as much as you did this week so they cut off your drip feed.
