This is just a suggestion, I haven't brought up the idea with Mo or Tamas, but perhaps if Mo stocked Bagaboo, being in Berlin they might be easier for him to get? Mo likes to have lotsa kool bags, he may even already stock them, but it'd certainly be easier to get from Berlin than from Hungary, specially since Mo is all set up for customers from elsewhere with his online stuff.
Then again there may be some duty or tax complication tween Germany & Hungary, even so, it would only drive up the price of the bag, the actual shipping, form of payment questions would all be solved. The prices are already good, covering the overhead for Mo would only be fair, and it'd be up to Tamas to make it worth Mo's while. Certainly he like happy customers, and anyone visiting his shop in person or online could be repeat business with all the cool stuff he gets.
