For all you ladies TTC and spending a lot of $$$ on brand opks.. ebay and amazon has really good deals on $4 for like 20 ovulation test and 5 pregnancy test and 100 ovulation test and 20 pregnancy test for like $15 and they work great.. I use them and they have worked in letting me know when i am ovulating and S+H is free and they get to your mail in about a week. Hope i help save you some money, TTC should not be so expensive..
