We order at least three bottles or more at a time from Jeffer's and get free shipping due to ordering more than $60 at a time. There may be a small charge for Express shipping, but it saves quite a bit. The vaccine usually has a one to two year expiration. We keep the Marek's vaccine in the fridge and the dilutent on the shelf. Also, be sure to get the kind with the bottle instead of the bag, if you use the automatic syringe.
