Fuel Points Hack for 8x?

So Kroger has a digital promo right now for 4x Fuel points for $25, $50, & $100 Visa / Mastercard Gift Cards through 01/21/2025. They also have the 4x Fridays going on every Friday.

My question is could you buy a $100 Visa gift card. Get 400 points. Activate the Gift card in the store on a Friday. Then use the gift card to buy your groceries, let’s say $100 worth, for 4x the points on Friday? You would essentially be 8x your fuel points for $104.95 = $100 + $4.95 (activation fee).

800 points = 80¢ off per gallon and you only spent $105.

Let me know if anyone has tried this and had success. Thanks.
