This is the biggest bollocks I think. If you if you already pay more than 30 for a pair sticks you are being ripped off. 10 is good and 20 is already too expensive.
Just pick some up, feel if they are strong and a bit heavy. Then buy it. Don’t ask for advice on these things because they will show you the cheapest one, then slowly introduce you to a more expensive one, ending up at the expensive line even if it doesn’t matter.
It’s not like you are buying a wandering magic stick from the Harry Potter movies, now is it?
These are the small profit things for the shops, don’t fall for it!
