stationer's vs stationary shop vs paper shop


Could you tell me which is correct?

  1. I work in a stationer`s.
  2. I work at a stationer`s.
  3. I work in a stationery shop.
  4. I work at a stationery shop.
  5. I work in a paper shop.
  6. I work at a paper shop.

Thanks a lot

The only ones that are bad are 5 and 6.

1 through 4 are fine, except that you need to use an apostrophe instead of a grave accent mark.
