I was recently browsing a shop. See the screenshot after hitting "Add to cart":
As you can see, the shop had about 20 colors in "New" and as many colors available under "Used". So, to add the selection to my cart, I had to scroll two whole pages down to hit the "Add to cart" button; then scroll two pages up to select a new color, scroll two pages down again...
That doesn't seem very convenient. And when I clicked on a new part located after this very long list, everything scrolled back up as the long list disappeared, and I couldn't see what I had clicked on (without scrolling back two pages up).
I really think this interface could be improved. I also couldn't see lot quantities when browsing the store without clicking "Add to cart" everywhere, but I have complained about that before...
Thank you for considering these concerns.
