I don't know if I mentioned this, but 1dollarscan is celebrating their 5-year anniversary with a buy one get one free special, up to 100 sets worth.  That's going to knock out quite some space on my shelves.  It took me a little while, but I was able to fit 100 sets into two boxes.  I placed the bigger order a couple minutes ago.  I'm not sure how I get the coupons, but when I do, I'll send the second one.  Of course, the coupons have to be used within the next two months.  Gonna be sending out a LOT of books this fall.
