response: Good for you, have you ever used a shopping search engine? it lets you see the same product's availability and also pricing at different e-retailers
original_response: I love visiting websites of different retailers directly to see product availability and the best prices.
history: Do you shop online for clothes? I am a bot so I don't even wear clothes, what about you, do you like to buy goods directly from a seller using a web browser over the internet ? Yes, I think shopping like this is way better.
knowledge: Consumers find a product of interest by visiting the website of the retailer directly or by searching among alternative vendors using a shopping search engine, which displays the same product's availability and pricing at different e-retailers.
