According to the old saying new sayings haven't stood the test of time just yet, thank you very much you should not put all your eggs in one basket. How old a saying it is, I don't know; I do know that Shakespeare wrought a variation on it in The Merchant of Venice. Says Antonio in the very first scene:
My ventures are not in one bottom trusted,
"Bottom," of course, refers to the bottom of a ship: Antonio, at least this early in the drama, is not so foolish as to put his entire year's inventory into a single vessel, what with the possibility of shipwreck and/or piracy always looming.
This past week, the local cable company, from whom I buy television service and Internet connectivity, sent me the umpteenth offer of a package deal, which would presumably cut my overall expense by a few bucks if I moved my landline telephone service over to them. As always, I threw it away: I am disinclined to put all my eggs in a single basket. The phone company (it's that big one you thought was put to death twentysomeodd years ago) has a package deal of its own: while their Net-based TV service isn't here yet, they'd love to see me move my wireless service to them and run a DSL line instead of cable. Not going to happen.
Nor do I bundle my insurance services together: I buy my auto insurance and a so-called "umbrella" policy from one firm, and my homeowners' insurance from another. The agent for the latter sends me a note every few months to remind me that I could see substantial discounts were I to buy all my insurance from him; I politely discard it. I also carry a couple of life-insurance policies, different issuers, even different types: one is a term policy, paid for through payroll deduction, and one is a whole-life policy, for which I send a check every six months. My health insurance is provided by, you guessed it, someone else.
This is by no means a new phenomenon: I have always done things this way. (Before I bought this house, I was a tenant, and I had renter's insurance, from yet another firm.) And while I'm not in the market for a second motor vehicle for one thing, I have a single-car garage, which is full it would probably not occur to me
