Dear [Friend's Name],
Thank you for your letter! I was happy to receive it.
Regarding your plans for shopping tomorrow, I also want to buy new jeans. It's great that you're going to the online shop; I usually buy clothes there too. It's convenient and there are often good discounts. Who buys food for your family? My parents usually do it, but sometimes I help them.
It's always nice to get your letters. Write back soon!
Best wishes,
[Your Name]
