Kevin | 24 February 2010 | 0 commentsLEGO Castle Building Set for $8.83. This product ships free if you have Amazon Prime or if you order a total of $25+ dollars worth of merchandise from qualified Amazon products. The set comes with a horse, a catapult, a knight, a drawbridge, flags, etc. The reviews are positive about this product. It should be noted that the LEGO Castle Building Set just comes with one wall of the castle (the front). However it should be easy enough to add 3 walls to the castle if the child who has this set owns any other Legos.
