From the website:
"Important: In our attempts to combat fraud, we can only ship to the credit card holder's billing address. Please ensure you list the billing address exactly as it appears on your credit card statement or it may be declined by our merchant bank.
We screen diligently for credit card fraud! We pursue all legal avenues - advise credit card companies, credit bureaus, and law authorities regarding any suspicious, attempted, or experienced credit card fraud."
TX billing address and CA shipping address threw 'red flag'
But then again....best not to supply the info requested due to lack of secure method (e-mail) and it could be 'phishing e-mail' that has nothing to do with AMain.com
Might want to contact AMain.com via toll free # 1-800-705-2215 (Toll-Free) and inquire???
