Letter Of Thanks For A Service Performed

Dear Ms. Jane,

Thank you for your letter of 10 February returning the draft of the catalogue we propose to send to our customers.

I am very grateful for the trouble you have taken to examine the draft and comment on it in such detail. Your suggestions will be very helpful.

I realize the value of time to a busy person like you and this makes me all the more appreciative of the time you have so generously given.

Yours sincerely,
