I don't have a problem with it--my mom does. She feels it's too complicated; that they changed the way it works too much. And plus her computer's slow, so she refuses to use amazon. She wanted me to look up other sites where she can just 'click and buy' so to speak, but as you can tell, there are barely any sites left that have the Sims 2. My mom doesn't like Ebay, most store sites don't have the base game, and most stores don't sell the Sims 2 either over by where I'm at.
Talk to her again about Amazon, it really is easy and it's one of the few reliable places left for finding Sims 2 games. I just bought three Sims 2 stuff packs for $30, including the price of shipping, and they were shipped within a few days. That's $10 a pack - not a bad deal at all, and they were all new.
Also tell her that if she gets an Amazon credit card (it's a Visa), all the purchases earn bonus points that can translate to more free stuff at Amazon. It's a good deal, but wait until they offer it with a gift card. They do that regularly to get people interested in the card and it's worth a nice amount, although I'm forgetting how much now - maybe $25? It's enough to buy another game.
When I make an Amazon purchase, I bundle them together so that I spend the $25 minimum to get free shipping. They have so much at Amazon, it's easy to do. I tend to do all of my Christmas shopping through them.
