I asked for 2 sausage mcmuffins with egg and got 2 with no egg and they charged me 4.73. I called and asked if they had the promo for 2 for 4 she said it was 2 for 4.50. So i told the girl on the phonewhat they gave me and what they charged me and she said. "Thats because those are 1.99 each." Even with tax at 9% (wich is not here in SB) it does not add up to that. I know its just change but my order wasnt right and they gave me less for more. I WONT COME BACK
