Budget shop I not sure if your area have the same scanario. But my town in Singapore having a trend of existence of many new shops that selling budget stuffs. These shops normally sell those small and lose parts that that are dirt cheap. When you passing by, you would definitely be attracted by its price tag of very very cheap. Eg $1 $0.50 this kind of stuff.

This shop that I passed by just now after dinner was quite newly opened roughly about 1 -2 years time only. But due to its products quite cheap and a lot variety . I did see many crowds anytime round. Not sure how the stall owner be having his/her meal as customers non stop. The environment did make passerby to take a look on their products even you did not have in mind anything to buy. But when you visit the shop , seeing the price tag, then you suddenly think of "what don't I buy to keep spare, who knows if I would need it someday later, wasted also never mind because it's dirt cheap" Haha , I guess most think the same as I do. So their business is a proof of my theory . Haha are you with us too ?
