Rite Aid

First transaction I did a Visine and a Poligrip; used $1.00 Visine in-ad q, $2.00 Visine insert q, Free Poligrip, and tried to use a $1.00 +UP reward. He scanned the +UP first, then the others, the Poligrip last. It kept beeping, saying no matching item found. He first tried entering it for $1.99, although I'd got 20% off, so I said try entering $1.59, but it still didn't work.
So he voided the trans and started over, using the Poligrip coupon first. He took off $1.99, rather than $1.59, so ended up I wasn't able to use the $1.00 +UP at all. No biggie.
Total $0.59 + .32 tax = $.91 from gift card
Rec'd $3.00 +UP = $2.09 Profit

Then I did four more transactions of just Visine;
$3.99 Visine (20% disc)
-1.00 in-ad q
-2.00 insert q
-1.00 +UP
= -.01 + .21 tax = .20 from gift card
Rec'd $3.00 = $1.80 Profit

Then two more of just Visine;
$3.99 Visine (20% disc)
-1.00 in-ad q
-2.00 insert q
= .99 + .21 tax = 1.20 from gift card
Rec'd $3.00 = $1.80 Profit

Grand Total $12.09 Profit
