Buying Aquarium Supplies Online?

In a research that measured the time between browsing a site and making a purchase, it was found that most buyers take their time before making any decision.

aquarium supplies took the highest with 92:50 hours between browsing and purchasing.

I wonder why the shoppers for aquariums need the longest time to decide. Are you going to shops to see the actual item and then return and order online if it cheaper after you verified the exact details of what you want? Is it because you wait from weekend to weekend to think about buying or improving your aquarium?

Love to think what you think.
