One issue I have with Amazon, is their wasteful packaging. I think they are trying to resolve this though. Recently, I ordered a mascara along with a few other items. The mascara was sent separately .. in a box that was big enough for dozens of the same. It could have been packed in an envelope.
The other day, I received 2 men's t-shirts and 6 pairs of men's socks in a paper envelope. The plastic packaging of 1 or the t-shirts had been torn open on both ends, and was scrunched up and wrinkled. I tried to lodge a complaint, but could find nowhere to do so. I finally left a complaint on the section where you rate the product .. but I know that's not going to go to the right place. I'm not returning it. I will steam the wrinkles out.
But, I digress .. I'm not sure Amazon stores will be successful. The stock would be fairly limited, I imagine.
