Due to unforeseen circumstances I was not able to join yesterday’s call, but looking at the link provided I’d say go for it - prices seem reasonable. I do not have a suggestion with regard to numbers but at least one pop-up banner (what are the size options?) and a few table top ones probably are useful
& I’d say all of them in English, as every European language is not realistic and I do not want to give any particular one preferential treatment ;-) But open to ideas from others who might want to use them in a particular language context, and if it’s only printing costs and not additional design work if we provide the text(s) ourselves, then I am totally fine with having other languages too...
