Cutting prices on the net

I've just placed an order on Amazon - Against All Enemies (following Matt Turner's recommendation), A Devil's Chaplain and Kind Of Blue - and I remembered the slightly media flurry a few weeks ago about the concept of 'Fifty Quid Man', that latest creation of the marketing demons:

"This is the guy we've all seen in Borders or HMV on a Friday afternoon, possibly after a drink or two, tie slightly undone, buying two CDs, a DVD and maybe a book - fifty quid's worth - and frantically computing how he's going to convince his partner that this is a really, really worthwhile investment."

But, it occurred to me that the internet, or at least Amazon, version is more of a twenty-five quid man - that being the amount you have to spend there to qualify for free shipping. I'm sure I can't be the only person to have added an item or two onto an order, persuading myself that it's good value for money to spend that extra cost on more books and CDs rather than postage and packing. Or maybe I am, and now you're all laughing at me.
