1. To purchase goods from an online retailer, as opposed to going to a physical location. For the sake of my bank account, I don't shop online as much as I used to—it was getting just way too easy to spend money! I was always suspicious of shopping online, afraid that my financial information would somehow get stolen.
2. To use the Internet to find or research potential purchases. Often followed by "for." Let's just shop online for a new table. I'd rather find something we like before going into any stores. You can save a lot of money on your insurance policy if you shop online for the best possible deals.
