Ummm..... I plead the fifth!
Seriously.... I buy a couple boxes of good ones when I am at the store during the 2ww. Dollar store..... the most I have bought at once is 12 ...I think

I tend to try to go to Wal-Mart when the pharmacy is closed. I think they must think I am nuts because sometimes I go back the next day if I peed on all of the ones I bought the day before.
I have to say that the ones I bought on Ebay are just as good (so far) as the dollar store and are about 45 cents each. I bought 25 for $10.99 (including shipping).
Man now I feel like I need to pee on something..... OPK here I come!!!!!!
