no, he didn't reply.
I contacted another company, and the price would be around 2200 HUF (8EUR)/ shirt, and probably only one colour shirt as an option.
I think this price is just around the border line. Should we go for it?
There is also an option to make the shirt with stickers. In this case it'd be cheaper (6EUR), but the quality would be bad, and it'd fade with washing. I don't think thats a good idea.
