Student or Learner
I don't quite understand the discount listed on the website. Does it mean that the gym fee per month is $499/month if I join it for one month, whereas is it $280/month if I join it for 4 months?
I'm not a teacher. I speak American English. I've tutored writing at the University of Southern Maine and have done a good deal of copy editing and writing, occasionally for publication.
The above paragraph is my email and the website belongs to one of the gym clubs in HK. Sorry for causing any misunderstanding.
Change 'is it' to 'it is' and your email is fine.
