Filler defined:
WAGS allows you to use the same amount (or less) MQ for the number of items you buy. For example, if you're buying 5 items and you have a MQ for each item, then you're unable to use an RR in addition to the 5 MQ because the RR is also considered an MQ. In order for you to use your RR (i.e. MQ #6), you'd need to buy one more item to bump up your item count to 6 also.
So, the filler is usually something cheap that we use to allow us to use one or more RRs. Sometimes, some smart couponers can get overages (negative total) on their bill. Fillers can also be used to bring the total to $0 or a positive amount, because some WAGS will not pay you $$ to take products home.
Here's a list of fillers that may be helpful with your RR, etc.
