Stacy went to a store to buy some pairs of shorts. Each pair normally cost $10, but there's a discount of 10% on the total cost for people who purchase 3 or more pairs at once. How much can she save by buying 3 pairs at once as opposed to purchasing them individually at different times? Let's think step by step and output the final answer after "####".

Without the discount, each pair cost $10 so 3 pairs cost 3*$10 = $<<10*3=30>>30
With a discount of 10% on the total cost, she can pay only $30-($30*(10/100)) = $<<30-(30*(10/100))=27>>27
By buying 3 at once in order to get the discount, she can save $30-$27 = $3
#### 3
