How have shopping trends changed over time?

I think the shopping trends have changed a lot over time with advance technology. In the past, we must had to go to a shopping center or a store to buy something at during the day time, besides we didn't  have no enough information about it. But nowadays we don't need to go to the store; we can get the stuff over the internet, the TV or even a Smartphone at any time. Moreover we can search the product’s information fully before buying, find reasonable prices as comparing the price of diverse online shopping centers through the internet. All in all, nowadays shopping is more convenient compared to the past. We don’t need to be restricted by time or space, and get more information not only producer but also purchaser**.

producer but also purchaser** Kelly, I am not exactly sure if you are saying that producers are also able to get more information of if consumers are able to get more information about the producers?  so this is how I would say #2  and get more information not only about the producers but also about other purchasers.

#1:  and producers are able to get more information as are purchasers.
