Can you tell me about some good deals on produce ?   The mangoes are on sale today .   What exactly are mangoes ?   They have yellowish red skin . It's a fruit with one big seed .   Is the seed edible ?   Maybe if you were a parrot . I wouldn't recommend it .   How much does a mango cost ?   Normally , they're $ 2 each . Today , they're only $ 1 each .   Maybe I won't like the taste .   It's hard to describe . They're sweet , but also sort of acidity .   How do I tell the difference between a ripe one and an unripe one ?   They're similar to an avocado . When the outside feels soft , they're ripe .   Where do most of them come from ?
