There customer service rocks ! I got a call today. I had ordered the answer keys & the teacher's guide. Turns out you don't need both ! So, they were crediting me for the answer keys ! I thought you needed both. They could have just charged me for both & shipped me both. Not to mention if you wanted to make it really cheap you could just order the answer keys no guide. I hope I like their curriculum.
I'll be ordering from them soon for the first time, too. Good to know they have that kind of integrity.
