Almost Free

I had another successful trip to Dollar General the other day. 

 There was a special, buy 3 airwick get $3 off.  So the 3 should have added to $18 - $3 = $15 so I could use the $3 off $15 survey coupon.  But I picked up the wrong kind and one was only $4.50 instead of $5 so that is way the gum is there, as a "filler".  I had a buy one get one free coupon, a 1/2 off coupon and $2 off coupon.

The cashier was determined to make them all work for me.  But in the process, she had to scan another one of my 3/15 coupons making the first one void.  So to replace the coupon she gave me a $3 gift card essentially making the transaction only  64 cents.  I think I could have done better if I didn't have to buy the gum.
