I thought I'd list this link for you to browse through. This mob sells DIY preg tests for cows (BioPryn brand). Unlike other places, these will sell the tests in any size packs you want, from one to whatever, whereas, other companies require you to buy a bulk pack. They only charge the cost of the test, so there's no extra fee added cause you only bought one or two. The price, from memory was only about $10 or $11 a test and that includes processing at the lab, and they email you the results back.
