Do you find online shopping to be a time saver or time waster?

I’m discovering that I waste a lot of time looking online for items that previously I would have just gone into a store and bought.
I recently wanted to get an electric fly swatter. Two years ago I bought one at Harbor Freight for $2. I needed an additional one for the garage.
Rather than going to HF, I started looking online. Amazon had at least 20 different models. I then needed to compare the advantages and disadvantages of each. 3 layer vs 1 layer, voltage, pulse rate, price, availability, etc. Then I started reading comments and reviews. Then I went to Fakespot to check the reviews themselves. And so it goes… I wasted 2 hours!
I could easily have driven to the store, shopped for half an hour and returned home in much less time. And certainly with a lot less frustration.
Do you have similar experiences?
