Financial management online and Price comparison websites are the ones that impress me the most. Websites like aliexpress, jiji, olx, ebay are some that i have used. And guess what, i do check prices there, compare it with physical stores and then take my decision. Online banking has transformed a lot of financial services. From paying for flight ticket to buying bitcoin when the price suddenly dips. I believe alot of unfathomable improvement and technological exploits awaits us.
