they all say the same basic thing, and many sentence show up exactly the same in all three letters. the only differences are the first two to three introductory emails, and the number and models of the computers.
they requested my name so that they may make the check for me. they also requested the billing and shipping address.

some of the grammar is incorrect.1 of the email addresses are from Yahoo! and the other is from gmail.

they all offered to pay shipping of the equipment, and say that they will provide the software.

should i be worried?
