I know my blog is full of grammatical errors. Its not a big deal because I am only a blogger. I am not a proofreader or expert or whatever. I blog because I want to blog. I write because I want to write. I am not selling anything on this blog, so any information or misunderstanding from your reading will not affect anything.
But.. if you write your advertisement for the purpose of attracting customers, you better be more careful with your writing. Even an error will cause you trouble.
Read the ads carefully. Manja is spoil/lovely in English. In this package, you will get free wife or internet. Free wife for a Lovely Package? This is an awesome deal.
