Two more Pentax deals in addition to the $100 price drop on the Ricoh GR II I reported a few days ago:
£100 trade-in bonus in the UK when you trade-in any working DSLR or CSC for the Pentax K-1 (offer ends December 31st).
In the US, the Pentax K-3 II camera comes with a free BG-5 battery grip (a $279 value).
