I want to write my minds:
1. I have more 80 plugins now at nopcommerce marketplace, I think I am the one of the bigger vendors of plugins for nopcommerce :).
2. Don't forgot that nopcommerce gave us an opportunity to do our business and to earn money.
3. nop team spent many time, effort and money for improving the performance of nop 4.30. Now we have very fast eCommerce platform. This fast and flexible eCommerce platform will give us the new customers and more money.
4. All vendors use nopcommerce marketplace for earning money. It's reasonable that we need to pay for it. Look for eBay and Amazon :).
5. I am sure that nop team will use this money for improving future releases of nopcommerce.
6. I have a lot of plugins and most plugins I sell several times per year. It's not reasonable to pay for these not popular plugins for me but I saw that I need to do it. Why?
a) I want to show to my customers that I have a lot of plugins, It's my portfolio
b) I want to show to possible customers of nopcommerce that nopcommerce has a lot of extensions. I am interesting to populate the nopcommerce. New customers of nopcommerce == new customers of my business.
7. to pay per day or to pay per purchase. I think it's better to pay day (month). I use the nopcommerce marketplace for my portfolio.
New customers of nopcommerce == new customers for my and your business
