I'm not uploading the image, because it's not worth it. But every one of these listings has a "Certificate" among the images, and everyone of them uses 3 i's in the word "Certificate". Someone obviously made a typo in the template. And yes, I'm familiar with the old excuse "Not everyone speaks English as a first language", and on a forum, it's excusable. But if I'm advertising a $40
thousand dollar camera in an English market, you'd better believe I will find SOMEONE who speaks English flawlessly and get them to do a spell check.
