Hello! I purchased what I think was called a bridge unit a couple of years ago. It has unit 4 of year 2 and units 1, 2, 3 of year 3 along with the bases for each of these years. I now need unit 4 of year 3 classic to complete that year but I can't seem to find where I can do that. Is this unit still available for purchase in the classic? Thanks for your help!

Hi,
Yes, you can certainly still purchase it! Go to the Bookshelf and click on "step 1." From there, you can click on Year 3 Classic.

Blessings,
