You can change your product listings any time, so feel free to experiment. Prices too high? Lower them. Reckon you can charge more? Raise them. Want to jazz up your blurb? Do it. Want more templates per collection? Or to include more thumbnails? Or add thumbnail images...? Well you might need to delete the old product and add a new one. But it's quick and easy and worth the effort to get it right. Next tip. Cheers, Danny (the pragmatist).
