buying ovulation and pregnancy tests in bulk

I'm am curious where you ladies get your ovulation test and pregnancy test in bulk. I was going to order from Amazon but have no clue where to start. In the past I've used frer pregnancy tests and clear blue advanced ovulation test... but since I've been trying so long I think I might be time to switch to a cheaper option.
