It's a day out. Bargins can still be had, but not like the 80s and early 90s, depending on what you are looking for.
I like to look, touch, and feel things before I buy them. Now that I've seen it, I may order it online if it is cheaper. If I need it now, I'll buy it.
Ordering online, you have to ask yourself if it's still cheaper after you pay shipping and transfer fees.
It's still the best people-watching events around.
