Tissue paper for you?

I know it is not always easy to stand along crowded places for long period of time monotonously to sell 3 packets for $1 tissue paper. Which is why, I have great respect for these people that the mere reason that they are doing this is for survival, mostly. Which is why I always buy from them.

Their 'sales' is not often due to demand and supply though the initial intention of this action of theirs is so. Well, by standing there, isn't it not to do business by filling up the need of those who need it and I can supply it - Basic demand and supply

However, the situation is such that many people buy from the person out of sympathy and not out of need. No need for it, but I still buy because I want to help the person. Kindness and willingness to help seems to be the main motivator for triggering the 'sales'.

However, one cannot deny that there is still this group of people who buy out of need and not out of sympathy (or at best, you can say killing 2 birds with one stone).

So my next question will be, to these group of people, does selling a higher quality tissue paper improves their 'sales' and turnover? I mean for tosthhose who buy out of sympathy, as long as it is tissue paper or rather even if it is not tissue paper, the 'sales' will still be effected.

However, for those who buy and will be using the tissue paper themselves, one tend to be more fussy and choosy about the quality, and given the standard market price of 3 for $1, be it any brand, good or otherwise, then will the good brands, given its better value-for-money be more sellable?
