MY E-SCOOTER TIRE DILEMMA: FINDING REPLACEMENT TUBES FAST!

Okay, so I totally/completely/utterly flatted my e-scooter tire this morning. What a time to, right? Now I'm stuck figuring out/trying to figure/dealing with where to find a replacement tube/tubes/one of those tiny tubes. It seems like every store/shop/place is out of stock. Ugh, this is driving me nuts/really bumming me out/sucks majorly. Perha
