Price is $12.99 for 32oz. I got 2oz. for $4.99. they didnt have the 8oz bottles, but i didnt know they made that size so i really didnt look.
Looks like the exact same test, although a post from JasonLion a long time ago said that it uses a different scale, so i guess its a different concentration. dang, if it works the same and you can get a giant bottle for that price, might be worth looking at the other kit.
