Good packaging and a small storage bag are also nice touches for accessories. Reviews that mention long term use are more valuable than comments written on day one. If they reply politely and give detailed answers, I feel more relaxed.
If anyone is interested in real user experiences, I sometimes write short notes about the shops I test.

I also started paying attention to how websites display sizing charts for clothing. For light summer tops I keep to my normal size to avoid a baggy look. Otherwise they become clutter in the closet after the trend is over. Comfort around the heel and toes is more important than super fancy design. I try to look for real photos of the insoles and soles, not only the outside of the shoe. When a store shows clear shoulder width, bust, waist and length, it is much easier to choose. Sometimes customer service can fix a bad experience, but not always. Taking a few minutes to research before buying can save a lot of money and frustration.
Hope this helps someone.
