I would agree on test strips. I have no clue why those are still being charged at 1.00 dollar per test strip. To be honest the test strip technology hasn't changed all that much in the past 15-20 years. I image they can make a test strip for a few cents. The remaining cost is in packaging and marketing (all those commercials). So I'm sure there is a 200-300% MARKUP on test strips. I imagine the true retail cost should be around .30 cents per test strip.
For Dexcom I can understand the expense, since the new technology is in its infancy. If you look at Dexcom as a company they are still losing money and have been since they went public. So at this point it isn't a money making enterprise its a money losing enterprise.
