One of the hard facts of "deal-making" today is that it's all unseen.
If I'm buying, I really haven't seen the merchandise not have I seen the person selling it.
Likewise, if I'm selling, I haven't seen the buyer nore if he has the stack of cash I'm demanding.
There is that awkward few days of limbo where the buyer has sent payment and nothing in hand to show for it.
Likewise, there is that awkward few days of limbo where the seller is wondering if the check will be any good or if the buyer had a change of heart and I'm missing legit buyers.
It's the new biz ...
