So gas in my neck of the woods is currently averaging about $2.20/gallon -- the maximum discount under the Stop&Shop/Giant MD program. What happens if the gas price is $2.199? Will the "computer" deduct 2200 points and charge me nothing: or will it only deduct 2000 points and charge me .199/gallon? If so, I'll want to find the station that's still slightly above $2.20 per gallon.
Does anyone know? It's a "problem" we haven't previously experienced because this is the first time gas has been this cheap under the promo.
