Very interesting!!
remind me of my old days..
I do sell things in school too. Guess what I'm selling in school
"Bread" erm... pads... $0.20 per pc.
I'm very well known for my "trade" in school cos all the gals know my price by WOM, so I always bring extra in my bag.
At that time, my grandma told me must collect "token" and must be even Number, if not nxt time no good for me.( But I nvr ask her why la) All my "customer" just pass me $0.20 and I just give her the goods. haha Sometimes teacher also buy from me...
Business very good, sometime out of stock...heehee
During my time, $0.20 per pcs very exp. but wat to do ... must get even no. so this is the best price n no discount!!!
so they better remember to bring their own, if not...hehe become my pocket money lo...lol
Anyway, little trade is ok, as long as they don't con their classmate, I think is ok.
