I'm interested in purchasing 2 or 3 of the 100 stem units from Costco. However, given that most grocery store bunches have about 10 stems a piece --- I'm trying to understand the value of buying in bulk. If a bunch is about $3.99 for 10 stems - how is $90 for 100 a deal? I heard someone call these grower's bunches, which differ from what you would see in a local store. Can someone please explain?
