You are right. Vodafone seems to only sell their "Freikarte" (free SIM cards without balance) online right now. The starter pack for 9.99€ with 1 month of Smartphone Special included is sold all over Germany in all Vodafone stores, many service stations, some kiosks etc. or with heavy discounts e.g. on eBay.de or Amazon.de like here.

Minimum top-up fee is €15 by top-up cards with Vodafone in Germany. But you can use 5€ for add-ons like 250 MB at €2.99 for extra data.
