Dear K.Kwang,
It needs to have more price comparison with other vendors, please wait a bit more, we shall get back to you today. Furthermore, we have some concern whether you are able to send via post for the print material in "Water drop" shape? Is it necessary to put it in the envelop first? Please check.
One more thing, please allow Procurement to have more time for price comparison for the next coming job, so that we will not end up to use only one vendor without any price comparison.
