I did not say you should be ashamed for getting free plants. Not getting them (and using them) would be dumb ;-)
I just mentioned that this is a bit misleading, because it is not new plants. Similar to other vendors that basically do 50% off almost the entire year. Then they should be honest and charge the real amount and not claiming the product costs twice the money.
by the way, Benny Govaerts also created some very nice free plants ( I think he is more on the Vue side of things) and there or other free resources out there - go and get that stuff.
