$423.99 for LEGO Icons Tropical Aquarium (4154 pieces)

Amazon has the LEGO Icons Tropical Aquarium building set for $423.99, which appears to be the current full retail price with free shipping.

This set features 4154 pieces and is targeted at adult builders, offering a complex and sizable display piece. The $423.99 price reflects the typical high-end retail price for such a large set. Since no previous or original price is provided, this appears to be the standard retail price rather than a significant discount.

The high number of pieces and the size of the set make this a noteworthy purchase for collectors or enthusiasts (though at full retail, it's a premium investment), but without a clear discount, this is more of a competitive retail price rather than a deal price drop.
