They might be Internet shops with a store front (that's a good way to put it actually) but there are a couple of benefits to a real shop :

1. You can actually SEE the box before you commit to the purchase

2. They can blow you off but it's a lot harder for them to ignore you if you're standing three feet from them and looking them in the eye. It takes practice and training to ignore someone in that situation and they don't get trained all that well
