In a Mega Event situation, you MUST purchase 4 participating items (in this case) to get the additional $4 mega savings ($1 per item). So, for example you have a cart full of groceries, but you count only 7 items. A filler item is what you grab to get your item count up to a multiple of 4 so that you can get the mega discount on all of your items. Preferably something very inexpensive that doesn’t require a coupon, because if you had a coupon – it’s probably already in your cart!
(all prices valid through 5/10 and prices below assume you purchase in multiples of 4 – mix & match)
