Hi Kavya,

How are you going to use this information? The brochures are not confidential, as we distribute

these to customers. The freight estimate is simply that, a price estimate. That is not confidential

either.

Hi Chris,Thanks again for your help last year. At the bottom of your emails, there is a note stating all

items in the email are confidential. Could you please confirm whether or not the mixer freight

estimate and the mixer brochures you provided are confid ential?

Thanks,

Hi Chris,

Thanks again for your help. I have one more question for you. Can you give me either the

weights of the mixers or the cost of shipping a mixer 500 miles? Or would that cost already be

included in the prices of the mixer you gave me over the phone? Any rough numbers you could

give me would be great.

Thanks again!
