Thank you for sending me the great item the other day. We are very glad.

We've just found another great item at your shop.

We're thinking to buy 10 pieces of this item, so could you discount to 400 dollars including the shipping fee?

We really appreciated you gave us a discount last time.

We're sure you have a lot of other amazing items too.
If you'll sell us this item with that price above, we'd like to buy another 10 pieces of the item.
If they are the wonderful items, we'd like to increase the number of the item to buy.
