That, or they slap huge markups for these otherwise unpopular products.
Try to find a popular 16-bit ADS1115 ADC on digikey. They offer SMD 10X2QFN chip for $8, 10VSSOP for $10, assembled adafruit board for $22 (!!!) or DFRobot board for $15 (exact same board is half the price on ebay).
In comparison, ADS1115 boards from aliexpress are $2.
