People that buy and pay for things online don't (and mostly can't) use cash. So without separating out the online and offline purchases this could be misleading. I do so few transactions offline that I just use cash for those few, low value, transactions. Since there are many places in the physical world that just take cash I might as well just use the one thing. I have a working debit card (the bank pretty much insists) but the added convenience isn't worth the low risk of getting it skimmed and the small loss of privacy. Eventually we will have to start making a distinction between electronic cash and the physical kind. Cash is still a distinct sort of thing, no matter what physical form it takes.
