UPDATE on the All detergent: (Wisk will be slightly more, because there is only a 50¢ coupon available.)
I just went out and tried this and it worked perfectly!
You will need 2 computers as you can only print 2 coupons per computer.
I bought 3 of the All detergent.
$3.50 x 3 = $10.50 (+tax)
Let them total it to get the $3 instant savings (reduces the total to $7.50).
Hand them (3) $1 off coupons - link below (reduced the total to $4.50)
Total out of pocket is $4.50 + tax or only $1.50 each - that's over 70% off the regular price!
Dollar General is having a great sale on All Detergent (I use the free and clear variety). It is normally $5 and on sale for $3.50 through the 21st of March. Plus, you can print a coupon for $1 off, making it only $2.50! That's a 50% savings over the regular price! You can also ad-match this to Walmart (if Walmart carries the right size).
Wisk would be $3 after coupon.
Be sure to print your coupons now, as some of these good coupons have printing limits!
