Last night I ordered a new computer.  I haven't upgraded for several years...it was time.

I ordered it from NewEgg.com and paid for it with Discover Card.  They have this feature called Secured Online Account Numbers.  It is pretty nice.  You log in and get new credit card number for each vendor that you pay online.  That number is only good at the vendor.  I did that last night.  This morning, I tried to use my card and it got rejected/flagged.  I also got an email and phone call from Discover.  I called them up and told them that I really did buy that computer.  Some people might find this annoying or irritating.  I think it is a good service.  I would rather this happened and error on the conservative.
