Rite Aid Trip

I made a quick trip to Rite Aid tonight to pick up a few freebies:

3 Clean and Clear Face Washes $5.49

Used 3/ $3 ad coupons

Used 3/ $2 printable coupons

Final Cost $.49 each

-

3 ACT II Popcorn $.99 each

-

1 Gallon Milk $2.79

(I always try to pick up a free gallon of milk with any $3 off $15, $5 off $20 ect.. coupon)

-

I used a $5 off $20 coupon

-

My subtotal was $2.23...

I only had 1 popcorn to start but the cashier told me my subtotal was not high enough to use my $5 off $20?? Who knows 2 extra boxes of popcorn will be eaten so no big deal.
