TO GET THE 4TH MINIFIGURE FOR FREE YOU HAVE TO ADD 4 OR MORE MINIFIGURES TO YOUR BASKET AND THEN CHECKOUT. Condition: as shown new and complete untouched and unassembled with all accessories, baseplate, character leaflet and original packaging.
100% genuine LEGO item taken straight out of an original display box supplied from LEGO. Unfortunately I can't fix this.
Instead please do the following. Please be patient - this won't happen immediately but it will happen.
So you must have a minimum of 4 minifigures in your basket.
