"common citizens" is

sight = to see, site = short for website.
Since it's in the past can should be "could"

But those stores arewent bankrupt one after another because the internet makde it possible for huge companies to service the offline markets withat a very low cost.

Internet when used as a proper noun has the in front of it "The internet".

Small retailer's life has become more difficult forbecause they have less incomes.

Past Tense "has become"

On the other hand, for the buyers, the stuffs are is more and more cheap, which is not definitively a good thing.

Stuff is implied to be a multiple so it does not need an s at the end.

But However cheap the stuff may be, if they don’t have enough incomes, however cheap the stuffs be, they could annot afford it.

You may say that those people can try to work for the big companies, but that won’t work, my friend, because the stuaff demand for the big oncompanies is small.

Future tense = Lost becomes "will lose".
This should probably be part of the last sentence rather than a new sentence.

past tense because we are talking about the past

But those stores arewent bankrupt one after another because the internet makde it possible for huge companies to service the offline markets withcustomers at a very low cost.

again, past tense, "at a low cost" is more natural

SThe life of small retailers life becoame more difficult forbecause they have less incomed lower profits.

Income is never plural. Income is more like salary; it is money someone brings in. Profit is for businesses.

On the other hand, for the buyers, the stuffsre are more and moproducts that are cheap, which is no definitively not a good thing.

products is the word you want to use instead of stuff, "definitely not" means not at all, no. "not necessarily" means maybe good maybe bad. I'm not sure which one you want to use here.

But if they don’t have a high enough incomes, however cheap the stuffs bproducts are, they couldan not afford ithem.

You may say that those people can try to work for the big companies, that won’t work, my friend, because the stuff demand for the big ones is small.

"because the stuff demand for the big ones is small." I don't understand this part.

gap is singular
