This is our FAVORITE holiday and we never go small! This will be the 4th year of the MELTZ MOB, giving ALL members 15% off all purchases for the entire year!!!! How do you join? Simply come in to the store on April 12 - NATIONAL GRILLED CHEESE DAY - and grab your membership card! MELT MOB RULES No we DO NOT give out cards for delivery orders. No you cannot pick up cards for anyone who couldn’t come in that day. No you cannot order online and skip the line (we actually turn those systems off for the day). No you cannot get a card the next day if you miss this one! No whining, crying and begging doesn’t work.
