>n the hopes of selling you a water purification system. Lowes I think does this also.

Noted; thank you! I've def. walked by the spinning carousel of test kits at the Home Depot check out before but along the lines of what you mentioned, figured there was a bit of a catch, so to speak. I'll have to stop by Lowes or Home Depot and grab one to check out the details. Appreciate the comment!
