The LEGO Ideas NASA Apollo Saturn V (21309) has been discounted again by 25% to $89.99 on Amazon. This is one of the sets that will be retiring by the end of the year so get it now while you can or risk paying a higher than retail price after it is no longer widely available in a few months. Note that this price is for Frustration-Free Packaging and there’s a chance that Amazon will ship it just with the product box. More often than not, it will ship in the cardboard box that it came in for additional protection.
