Bro, Good for you and your "HAPPY" customers. I am not saying anything that should offend you. I merely pointed that these can be had at much cheaper price. thats it.
You are the one who is trying to selling something here, I wonder how did you get this idea than I am trying to sell you 30 pieces at 150 each so that you may sell them to others at 1000 each. thats absurd at best.
Regards.
Bro, OP is demonstrating typical "Extortionist Behavior". I am sure everybody must have faced this behavior at some point, specially while buying sunglasses. if you question the price and confront the seller (or extortionist), he/she typically replies by saying "ok! I'll give you money to buy me 100 items at this rate". lols!
Regards.
