LOL, 3 pages already!

It's mostly when it's in an article or some other type of formal or semi-formal context that the grammatical bugaboos really bother me a lot. I've seen a few articles on supposedly big-name media sites with these exact problems, and the coupon announcement here was the last straw. Hopefully, whoever wrote the copy for it won't feel that I was singling them out, because that wasn't my intent. I think they may not even be a native speaker, in which case there should have been someone to proofread it before publishing took place.
