I haven't tried, myself, but around here the easiest (allegedly!) way to buy crypto with cash is the Coinstar change machine at our local Safeway. I don't know what sort of commissions they charge, but you can get Litecoin there, as well:
Don't know if you have any such around where you are, though.
Now that's interesting, will have to check my local area and see. Thanks for that helpful tip! :)
You're welcome; good luck!
