Is they a freebie website, where I can get free box of cornflakes on regular basis

Unfortunately, there is no such website offering free cereal boxes on a regular basis. However, we would recommend checking out a reward and loyalty program website if you're looking to cut down on grocery costs. Several large grocery brands run loyalty programs where customers can earn points towards free products. Additionally, some websites, such as TopCashBack and ShopAtHome, offer cashback rewards for online grocery purchases.
