Gender reveal?

Sabrina • FTM, Baby Boy due January 15, 2019. 👶🏻💙

We have our anatomy scan next Tuesday and a gender reveal party the following Sunday. I want to do the confetti cannons but I can’t seem to find them somewhere I can pick them up in person or have them shipped quickly enough. I think I may have to go through Etsy and pay for expensive shipping just to be safe but reviews about still not getting them on time have me worried. I’d love any tips or suggestions on this!
