Schneidersladen is often expensive compared to others and they don't make good prices even for loyal customers.
"even 5% is hard for us to do in this times" ... come on ... i know people who work(ed) there and i know the prices THEY get.
To give 10% to loyal customers would not be a problem at all.

I don’t personally find Schneidersladen more expensive. When it comes to European brands of modules, I find them (and Thomann) cheaper to be frank. Bear in mind that most prices on European sites are inclusive of VAT ( 19 or 20%) while American sites do not include any sales tax.
Being outside the EU, I don’t pay the VAT and modules (EU and US manufactured) can be imported duty free to where I live. Customs locally only collects a 5% federal tax and there is a small brokerage fee to clear it through customs.
As far as Modular Grid is concerned, I never paid attention to the prices listed on modules and to maintain it up-to-date would have to be a nightmare.
