Personally I'd never buy anything from an unsolicited email. Unless it was someone you've bought from and subscribed to it shouldn't be getting past your email filter. Personally I wouldn't even open it. Ban the sender and report as spam unless you subscribed. Check your filters.
I never ever buy anything from a ciold caller nor from a spammer. No exceptions. If someone has a good product to sell for a decent prize they don't have to resort to that kind of marketing to sell it.
I once responded to a Nigeria-letter that came is private message on a forum by explaning to the "dame in distress" how she should buy a rope and look for a suitable tree and tie the knot and hang herself and suddenly all roblems will be solved. I also offered to reimburse her heirs for the cost of the rope once her death by hanging is confirmed by a trustworthy independent source :twisted:
I wonder if "she" ever did read my reply......
