Subject: Inquiry about the Exchange Scheme

Dear Sir,

I saw your advertisement in Amar Ujala today, where you have discussed regarding an exchange scheme. The scheme is regarding the exchange of old utensils with the new non-sticky cookware. I have some old utensils, which I wanted to exchange against the one offered through the exchange scheme.

I request you to kindly explain more about the scheme and all its terms and conditions. Also update me if there is a possibility sending and receiving the items through parcel, or the physical presence is mandatory.

Thanking You,

Your’s Sincerely

Archit Gupta
