The LEGO Ideas / Cuusoo 21109 Exo-Suit will be retiring soon in the European and Oceania (Australia/New Zealand) market. If you don’t have a copy yet, make sure to get one as prices for LEGO Ideas/Cuusoo sets tend to get pretty high in the aftermarket.
Plus, until February 28th, LEGO Shop at Home will be offering a free LEGO City Demolition Driller polybag with purchase above £25 (UK). Other European countries may have different thresholds.
