UK dealer WEX is giving away a Canon EF 40mm f2.8 STM lens, worth £169 (one of my favorite lenses) when purchasing a Canon EOS 5D Mk III. Further, Canon is offering both Adobe Lightroom 5 and Premiere Elements free when bought with the Canon EOS 5D MK III (or Canon EOS 6D) worth a further £180.
Please see here for details. With each product sold I get a small referral fee (but that doesn't cost you more, as it's paid by the retailer)
