the one for 6.99 is cheaper
$6.99 rounded to $7 X 2 =$14 for 90 fl. oz
so $6.99 is cheaper
get the 25 fl .oz because it obviously cheaper than the a fl oz
Step-by-step explanation:because i would not pay $7.00 for a fl .oz
when u can just get 25 fl oz for $4.00
so just get the 25 its cheaper
The 6.99 one because it has more detergent in it. So you get more from your money.
