So the way to really milk earning points on variable VGCs was to stack the $X off your $X purchase offers, and get cash back when you did not spend enough.

The following offers are available each month:

$10 off $10 - 7 rewards
$7 off $7 - 5 rewards
$5 off $5 - 4 rewards
$4 off $4 - 3 rewards
$2 off $2 - 2 rewards
$1 off $1 - 1 rewards

The total comes out to $29, and you need 22 rewards to redeem them all.

The second part comes into play with the department specific offers:

$7 off a $7 in the meat department - 4 rewards
$3 off $3 in the produce department - 2 rewards

To add all these offers you needed a total of 28 rewards.

So what you do is go to the meat department, dig through the meat packages and find one that was as close to $7 as possible, but not below, then go to the produce department and try to get as close to $3 worth of produce, but not below. By doing this, you trigger the $7 off $7 meat offer, and the $3 off $3 produce offer for a total of $10 off. Because the items in the purchase were over $10, it also triggered all of the $X off $X offers, for a total of $29 off. The total value of the money back offers is $39.

The transaction would have $10 worth of items, but $39 worth of credits. So you could get a maximum refund of $29 if you bought exactly $7 of meat and exactly $3 of produce.
