Interestingly enough, the first pregnancy test retailed for roughly $10 in 1978, which isn’t all that different than today’s modern version. Only now we have more price point options. Like the Dollar Store.
For just a dollar, you can pick up multiple kits, pee in a cup, use a tiny dropper and conduct your own science experiment on the cheap. It’s not as convenient as the "pee and wait" system of their name-brand contemporaries. But for $1, it’s easy enough to get the job done with the risk of a just a little pee on your fingertips.
