How Amazon uses "surge pricing," just like Uber

And as soon as Ahoolee would be fully launched, this case would be usefull because all sales will go to another retailer if amazon decides to cheat that way!
i think most online retailers resort to that tactic. i remember seeing a pair of emerald earrings very reasonably priced, so i clicked on the item. then proceeded to check what other items were being offered. When i returned to item that piqued my interest the price displayed was much higher. so i closed the ad and flagged as not interested in that company's ad. have never seen that company's ad ever again. Best to boycott companies that resort to such pricing strategies.
