what to do !? presents or none?

I called my ten year old daughter in the room to ask her what she finally wanted for Xmas. As we were looking online my 7m old pulled her hair as she's in that stage of grabbing everything and my daughter said "FFFFF....." as if she was gonna say fudge again... yesterday she said fudge and I put her on time out now she sounds the letter "FFF" ... I got livid and sent her out of my room to go change out her uniform. I slammed closed the laptop and left everything in the cart (It's cyber Monday so I'm trying to get some deals) Do I not get her presents or is that too extreme!? If so what do I do?? I need to get them today cause of the deals but this just happened. I don't want her to think it's okay! (I curse like a pirate) she's never repeated it bc she knows better. She's always known the rule that she can't say what she hears and has been exceptionally good at not repeating. I don't even know what she sounds like saying a bad word. Advice ladies please
