Shipping speed is not everything, but extremely slow delivery is very annoying. It is interesting to see how different people value different aspects of a product. For daily use items I try to balance price, build quality and real user feedback. If a website gives a detailed guide for measurements, I feel more confident when ordering. Taking a few minutes to research before buying can save a lot of money and frustration.

If anyone is interested in real user experiences, I sometimes write short notes about the shops I test.

If buyers say the item runs small or large, I always adjust my choice accordingly. Sometimes a store looks great in ads but the real product is completely different. A simple pair of glasses or a basic jacket that always works is worth a lot. Sometimes customer service can fix a bad experience, but not always. Whenever I find something that actually works well, I tend to reorder it later. I have learned to avoid items that look extremely different in every product photo. For example, I compared cotton, polyester and mixed fabrics for similar clothing items.

Hope this helps someone.
