The Better Business Bureau states:
if it is too good to be true ............Don't
Same with Security:
If someone will not apply the norm in Https or ...... Don't
Call them up and say Hey I wish to buy your product but ........
Valid Business people want your business and your next purchase.
They do not wish to sell junk and say goodbye.
Checkout any company with the BBB and call them if they are not listed and ask why ?
example : Doug the Drug on the Corner selling Crack is NOT a BBB candidate. Nor is Trish the Dish.
Common sence -- Yours should tell you that.
Example 32 : Callme. I will bill a Holiday on Your credit card. Free Travel. Mine.
