Yes, I certainly suggest getting a sealer for yourselves. I have one as well. I freeze vegetables from when they are in season for the winter months.
But the Wine'ing butcher is doing it so that you can call them up from say from MA and order your steak house tips that you like, from them and they will ship it to you, sealed and in a container. Or do it for your ride home from the Lakes or wherever you live. That is why I was mentioning it. I am sure they will vacuum seal it for you to store in your freezer as well. For those that do not have a bag sealer.
