In the past week, I have bid on 7, yes 7, Clear Plan Fertility Monitors on e*bay.
Lo*Mart apparently stopped carrying my peeonthem dip strips, which were super-cheap (or maybe I just need to go to ghetto Lo*Mart like I have been doing instead of going to hillbilly Lo*Mart like I did over the weekend).
I ended up buying 2 boxes (14 tests in total) for $24, which works out to a price of $1.71 each. My other ones were 20 for $17 or a unit price of 85 cents. Now, I'm no genius, but it looks like I am paying twice as much and the packaging is harder to open. And I'm not even sure 14 are enough (although I had 3 left from last month that I used first). Seventeen ought to be enough.
