Ok so I got really lucky today
I went to use my 4/20 email coupon again
I bought the following
2/2.00 Dawn deal
2 Listerine for $3.49
3 bandaid's for 1.99
1 Oral B toothbrush $6.99
Used
2/1.00 Listerine coupons
$9.00 ECB coupons
$4/20 coupon
$6.48 OOP
I go to leave and realize that the Oral B was the wrong one as they were sold out so technically I was paying full price for a $5.99 set
So I returned them and that meant that my first order which was $21 was actually only $16 and I got the $4.00 coupon -
But here's the odd part
My 1st receipt says
Subtotal $5.94
tax 6.75% .54
Total $6.48
BUT my refund receipt is
subtotal $5.99-
tax 6.75% .40-
Total $6.39-
Not sure how the calculated the first one - but it's obviously wrong. Guess I need to watch this closer.
