Regarding email offers: Please remember that email could come from anywhere. Unless you know the person or company from which you get any specific email treat everything with extreme caution. Many of the so called "offers" are not from this country which means that they are probably not regulated at all.
We also know that most (if not nearly all) email offers are scams or at best shoddy products. If it looks too good to be true. Or if it is misspelled..especially when it is emailed to you......IT IS A SCAM!!!!!
Remember that email is free for spammers...other that the cost of computers. So they have not even invested money in advertising costs. They are not just looking for profits...they are looking to rip you off.
If you want to stop the spamming - DON'T BUY FROM THE SPAMMERS!!!!
