Did Oxbow just change from a 5lbs bag to a 3lbs bag at the same price

I just bought a new bag of Oxbow in the new packaging. I still have the old bag at home the old bag is a 5lbs bag and the new bag was only 3 lbs. I thought it felt light. I am trying to find my old receipt to see how much the 5 lbs bag was but I am pretty sure it was the same price. Has anyone else boguht a bag was it 3 or 5 lbs. If this is true then Oxbo just drastically increased their price.
