It is a personal decision. Do you pay extra to support local small business who would go out of business and you would lose them if you don't, or do you look towards immediate personal gain and go for the least cost to yourself ? If something is not valued and supported, then maybe it ought not remain.
Recall also that it is the actions decided upon by the community that counts since bucking the trend may make you feel virtuous but won't have the desired effect. This is why so many unfortunate changes are occurring in society as folk follow the bribes and claim it foolish to do otherwise. Folk are so easily led; small gains, or free cakes & circuses, although there is some mileage for some in claiming they can not afford to do otherwise.
