I just had to give this update about my quest to buy Learning Language Arts Through Literature on ebay.
I ended up paying $10.73 for the orange book and $7.99 for the yellow book (prices include shipping). These books retail for $25.00 each and CBD has them for $21.99 each. I got both for less than the cost of one!
I will have to buy the student workbooks, if I choose to use them, but this was definitely a great deal.
