I spoke with Tanya this morning, who was very sweet! She said that yes I could buy individual pieces, but that they couldn't offer a discount on the individual parts. I am specifically looking at buying just the phonics and when we added up the cost of just the phonics & readers the price was almost as much as the discounted price of the whole kit. She suggested buying the kit and selling off the pieces I don't need. She said everything is resellable, even the curriculum guide, as long as you don't copy it TO sell.
The discounted price will be available through late spring and they will be coming out with a 1st and 2nd grade kit sometime soon ( I think she said late summer). Also wanted to add that some of the items from the k kit will be used in 1st grade.
HTH someone else!
