Well I don't use it for "crap I don't really need." When I get paid, I go on Amazon, get things I need for the house all at a cheaper cost than going to Walmart or Home Depot or whatever, and all delivered for free. Shipping for the things I've bought this month alone would have been far above $80. It's also especially helpful when I need something in particular. Maybe a new charger because mine broke, or a new cord for an amp, things like that. Instead of paying triple or quadruple the price at Best Buy or Radioshack, I can have it the next day for four bucks. I get a lot of food off of there, as well. Kitchen stuff, home stuff, headphone stuff, electronics, snacks, etc. All come from Amazon for no shipping whatsoever. I've ordered at least 100 things off there in the last few months. Even big things like desks, air conditioners, fridges.
