I purchased online a 5er of a house blend. They were packed uncelloed in a sealed bag. However, one of the sticks had two beetle holes. I contacted the retailer and they said to throw that one out and they'd send a replacement. Is that right or should they have sent a new 5er? What are teh chances that the other four are contaminated/infested? Did the retailer do right or did they only do 1/5 right??
