Chewies Help!

Looking for help on where to buy Chewies, as I want to make sure to do everything possible that my teeth will track well in the aligners this time.

I'm in the US, shipping would be preferred as I don't have a vehicle. I tried to buy some on Amazon that had good reviews (and were a cute purple color) but I've just opened them and realized they are strongly scented (or even flavored, no idea) in something sweet/fruity. I have some serious allergies and am not willing to take the risk. So I need plain, basic chewies, no flavorings or whatever.

Any advice on where to buy from would be appreciated!
