Can anyone give me a sub?

I'm a bit short of the readies at the moment. Well am I if I am going to take up an offer that appeared in my inbox this morning.

For the first time ever a spam email captured my attention. Go on, just try and guess what I was being offered. Viagra? No. Herbal remedies? Nope. A free pass for a porn site? Sorry no.

The offer, absolutely honestly, was for cut-price submarines. Real ones.

Now as much as I hate spam, I can understand the logic behind sending everyone sex offers. Most of us have sex from time to time and therefore can loosely be regarded as a target audience. 

But how many people buy submarines as an impulse purchase? How does it work. Do you just click through on the hyperlink and pay on your credit card? Perhaps they have Paypal.

I better investigate whether they deliver or whether it's buyer collects - from the seabed 20,000 leagues down.
