Since Abeka curriculum is so popular, used Abeka books are fairly easy to find. Here are some tips on finding the best books at the best prices.
The best places to find books are on the Internet, from people you know, and used curriculum fairs in your area.
On the Internet you can look at places like eBay and Amazon where people are able to sell their own Abeka books. Amazon lets people choose the price they would like to sell their item while eBay lets them choose the minimum price they would like and the price can go up from there. If you want a quick transaction, you might want to go with a website that has a set price like Amazon or homeschoolclassifieds.com.
If you like to take your chances, you can use eBay. You might get a good deal there or you might end up competing with others to get the book or set that you want.
If you know people in a homeschool group or from your church that use Abeka, you can ask them if you can either purchase or borrow the books they are not using. Sometimes moms are willing to share books if they have children that are not using them right now but have other children that will use them in the future.
You could also set up a swap system where you purchase one years worth of curriculum and another family purchases another year and then you swap curriculum after one year of use.
You can save a great deal of money on homeschooling if you are willing to purchase used Abeka books. You can use parts of the Abeka curriculum or a complete set.
Although Abeka is preferred by many parents, it is not the only option you have for homeschooling. There are many other curriculums and methods of homeschooling that work just as well, if not better, than Abeka for many families.
