There is nothing objective here.
You do realize that a store can change prices tomorrow. A new owner can buy the business in 5 years from now and can lower their costs on all items completely. Yet a quick Google search of the store will lead potential customers back to an old CR thread.
That in itself, now or in the future can label a store indefinitely. Do not discount the power of your voice DY! People can be swayed by your comparison. That’s why ordinary people get paid to write reviews.
