The factors that increase price sensitivity from the provided choices are:
- There are many substitutes.
- The benefits from purchase are less significant.
- The buyer also pays the bill.
- It is easy to make price comparisons.
- The cost to switch is low.
These factors generally lead consumers to be more aware of price differences and more likely to change their purchasing decisions based on price. On the other hand, having few substitutes or a relatively large expense typically decreases price sensitivity.
