You do not have enough information that what tye of payment method will you accept? Will you want that dollars in Bitcoin form? if you will ask for bitcoin then it is OK. I will also inquire about that what is meant by rs along with $2 after a slash you have written 200rs. Please explain it too.
By rs he means INR indian rupees.Anyway I would like to inform op that 200INR is around $3.4,why is he charging high rates if some one pays in ruppe?Or do you mean something else by rs?
