The Pharmacy "CVS" has the ContourUSB meter on sale for $9:99 without coupon.
And if you go to http://www.simplewins.com
you can get a $20 coupon making it free.
This is a very nice meter that plugs directly into your USB port on your computer and has integrated software for tracking your readings.
I Personally use this meter and highly recommend it to anyone trying to understand their Glucose levels.
BTW, there doesn't seem to be a limit I bought two without issue.
