MODEL ANSWER:

Dear Sir,

I am writing in response to the advertisement that I read in the newspaper couple of days ago regarding online selling of used products.

I have a blue shaded single door refrigerator, that was in use for the past six months. It has a very beautiful light colored butterfly print on the door wall. The refrigerator has ten years warranty and has the capacity of 300 litres. It appears small outwardly, but it has the space to store all necessary things.

I bought it in July, last year for 600 dollars. The only reason I am selling this is because I am moving from Denver to Washington and the cost of shipping this item is quite high. So, I am looking to sell it for 500 dollars. I assure the product is really worthy.I am available on 87..99..78..76 from 7 am to 8 pm and if I am not reachable, you can mail me at xyz123@gmail.com. Photos of the product is attached herewith.

I look forward for a prompt response.

Yours faithfully,

Jackson
