I would just go with Zenni, but if for some reason you can't or don't want to: - Fielmann is likely the cheapest with in-person stores and optometrists, but of course significantly more expensive than the online options. I believe they exist in many countries, although there may be better local alternatives. - brillen.de and brille24.de are two options that used to be decent, but may have changed in the many years since I used them (especially the former seems to have raised prices significantly). Probably only ship to Germany. One of them also used to offer local service at an optician if you needed adjustments etc. Shipping times can be long even with "local" online stores because they have the glasses made abroad (typically on the same machines everyone else uses).
