Originally, in 2021, masks in a chain store sold for $39.9/30 pcs, a pack of 30 pcs. I think the price is reasonable, $100/90, bought 3pack.
Today, I go to that store again, $19.9/30, buy 60 pcs, i.e. two packs.
When I pay, the clerk said that if you buy $68, you can exchange a pack of 30 pcs for $10, which is $9.9 further reduction.
At the peak period of the pandemic, it was sold at $39.9/30. On August 12, 2022, it was $10/30, a 75% reduction.
This proves that merchants believe that the pandemic is almost over, and they need to clear their inventory asap. Most businessmen are clever and will not do wrongly in most situations.
