I was at an Ultastore in Frederick, MD and checked the Redken section for their Curvaceous Ringlet stuff. They had the entire line of Fresh Curl products marked down with red tagsand their current Buy 2 Redken products, get 1 free still applied.

Original price: $ 19.00
Reduced price: $ 14.25
Buy 2 Get 1 Free: Each was about $ 10 with tax

Counter person explained they are changing the bottle design on this line of products, so definitely YMMV – but you might find similar deals at other stores who carry these products.
