Of course we all have different taste, but patterns still appear in long discussions. If the first order goes well, I slowly try more products from the same place. A good store usually answers questions quickly and does not hide behind canned messages. When I test a new shop I usually start with one or two items instead of a huge order.
If anyone is interested in real user experiences, I sometimes write short notes about the shops I test.

In the past I have wasted money on items that looked good in photos but felt cheap in real life. People who share height and weight information make it easier to choose the right size. That is why I sometimes leave comments myself when I test a new shop or product. Sometimes I even measure an existing frame with a ruler before ordering anything new. Metal can feel more premium, but acetate can be more comfortable for long wear. Many people do not mind waiting if they understand what is going on.
Hope this helps someone.
